A glass rod rubbed with silk is brought close to two uncharged spheres in contact with each other, inducing charges on them as shown in figure. Describe what happen when:- The glass rod Is subsequently removed.

A glass rod rubbed with silk is brought close to two uncharged spheres in contact with each other, inducing charges on them . Describe what happen when:- The spheres are separated far apart.

A glass rod is rubbed with silk:- Is the mass of a body affected on charging?

A glass rod, when rubbed with silk cloth, acquires a charge 1.6 x 10^(-13) Coulomb. What is the charge on the silk cloth.

A glass rod rubbed with silk found to have acquired a positive charge 6.4 x 10^-7 C. In the above process charging is by

A glass rod is rubbed with silk:- Name the scientist who establish the above said type of charges.

When a glass rod is rubbed with a silk cloth, charges appear on both. A similar phenemenon is observed with many other pairs of bodies. Explain how this observation is consistent with the law of conservation of charge.

A charged metallic sphere A is suspended by a nylon thread. Another charged metallic sphere B held by an insulating handle is brought close to 'A' such that the distance between their centres is 10cm as shown in the figure (a). The resulting repulsion of A is noted (for example, by shining a beam of light and measuring the deflection of its shadow on a screen). Spheres A and B are touched by uncharged spheres C and D respectively as shown in the fig (b). C and D are then removed and B is brought closer to A to a distance of 5.0cm between their centres as shoen in the fig(c). What is the expected repulsion of A on the basis of Coulomb's law? Spheres A and C and spheres B and D have identical sizes. Ignore the sizes of A and B in comparison to the separation between their centres. '(##VPU_HSS_PHY_XII_CO1_E01_005_Q01##)'

A long resistance wire is stretched between two iron nails. A battery of 2V is applied across the wire. One end of a torch bulb is connected to nail and other end is made in contact as shown in figure. - What happens to the reading, if we change 2V with 3V during the time of reading

A long resistance wire is stretched between two iron nails. A battery of 2V is applied across the wire. One end of a torch bulb is connected to nail and other end is made in contact as shown in figure. - If this wire slides over the resistance wire from nail 1 to nail 2, what happens to the brightness of the bulb.
