A glass rod rubbed with silk found to have acquired a positive charge 6.4 × 10-7 C.

1. In the above process charging is by

  • Induction
  • Conduction
  • Friction
  • Electromagnetic induction

2. Regarding above process which statement is false

  • glass rod loss some mass
  • silk gain negative charge but no mass
  • Silk gain charge arid mass
  • Total charge of the silk glass system is zero

3. Will the above process obey law of quantization of electric charge? Clarify your answer by finding numbers of electrons transferred to silk.

1. In the above process charging is by:

  • Friction

2. Regarding above process which statement is false:

  • Silk gains charge and mass

3. yes

Number of electrons transferred to Silk,

n = \(\frac{q}{e}\) = \(\frac{6.4\times10^{-7}}{1.6\times10^{-19}}\)

= 4 x 1012
