The glass rod has a deficiency of electrons acquired a positive charge while the silk cloth acquires electrons, therefore acquires a negative charge. a. Besides the attraction or repulsion of the charged rods towards each other, a good thing to show the class is the attraction between the rod and the cloth with which you have just rubbed it. E) electrons are transferred from the rod to the silk. 1st Edition. calculate the velocity of the body​, differenta between resistance and reactants ​. 1) As an example of the friction method, a glass rod rubbed with fur becomes negatively charged, but if rubbed with silk, becomes positively charged. When a glass rod is rubbed with silk, it becomes negative−yet both attract dust. Text Solution. Glass rod and silk. College Physics. the silk cloth acquires negative charge due to gain of electrons. In general, metallic ropes are suspended on the carriers taking inflammable materials. Since, the measure of charge is same on both, equal amount of charge with opposite nature will cancel out each other. Physics. ** 3. He was the first person to attempt to measure it directly, though other, indirect, measurements preceded his. Does the dust have a third type of charge that is attracted to both positive and negative? Hope this helps A. to conform to the conventions adopted for G and m in Newton's law of gravitation because . When a glass rod is rubbed with silk, it becomes negative−yet both attract dust. Two glass rods rubbed with silk in this manner will repel one another, since each rod has positive charge on it. When a glass rod is rubbed with a piece of silk cloth, then: (a) The glass rod and silk cloth both acquire positive charge (b) The glass rod becomes positively charged while the silk cloth has a negative charge. It is because the free electrons in the glass rod are tightly bound as compared to that in silk piece. Anonymous. Different materials have different electron affinities, meaning electrons will tend to gravitate towards certain materials over others. What is the role of ribosomes in protein synthesis? Favorite Answer. Does the dust have a third type of charge that … This happens because _____ A) electrons are created on the rod. The glass rod acquires a charge of `+19.2xx10^(-19)C`. B) electrons are transferred from the silk to the rod. lt br gt (i) find the number of electrons lost by glass rod. (c) and the cloth both acquire negative charge. the glass rod acquires a positive charge due to loss of electrons. 3 risposte. D) electrons are transferred from the rod to the silk. Does the dust have a third type of charge that is attracted to both positive and negative? The reason is (a) to control the speed of the carrier. Paul Peter Urone + 1 other. The electroscope thus charged is exposed to X-rays for a short period. Biology. Solution for When a glass rod is rubbed against silk, which of the following statements is true? A glass rod rubbed with silk is used to charge a gold leaf electroscope and the leaves are observed to diverge. Maths . Different materials have their electrons bound with different strengths. B) protons are transferred from the rod to the silk. Required fields are marked *. You can, of course, do the same thing with the glass rod and the silk. b. This demonstration illustrates two things: Triboelectricity and the electrostatic force. A glass rod rubbed with silk is brought near the fur rubbed with an ebonite rod. C) the glass rod was rubbed very vigorously with the silk. What are the postulates of Dalton’s atomic theory? Solution for When a glass rod is rubbed against silk, which of the following statements is true? NCERT RD Sharma Cengage KC Sinha. Biology. The electroscope thus charged is exposed to X-rays for a short period. How can a neutral atom attract electrons when it’s supposed to have zero charge? when a glass rod is rubbed with silk cloth, some of the electrons are removed from the atoms of the glass rod and deposited on the silk leaving negatively carged and glass positively charged. This leaves a net negative charge on the material that has gained electrons, and a net positive charge on the material that has lost electrons. When you rub the glass rod with the silk, the rod charges positively. (b) to keep the centre of gravity of the carrier nearer to the earth. (d) becomes negatively charged while the cloth has a positive chargeAnswer(b Explain.

NBC host to Trump: 'You're not like someone's crazy uncle' ESPN Falcons reporter Vaughn McClure dies at 48. View Answer. 1) As an example of the friction method, a glass rod rubbed with fur becomes negatively charged, but if rubbed with silk, becomes positively charged. Your email address will not be published. Risposta preferita. Figure 2 shows how these simple materials can be used to explore the nature of the force between charges. Explain how computer hard drives and graphic tablets operate using magnetic induction. Explain. Electrons are… b. We also build into the model that unlike charges attract, explaining why a glass rod rubbed with silk will attract a rubber rod rubbed with fur – a rubber rod rubbed with fur must acquire charge of the opposite sign to a glass rod rubbed with silk. In this case, electrons will be transferred to the cotton from the rod (since cotton has a greater electron affinity-which means wants more electrons).
