Question

please give me solutions of these questions.
these are from the chapter electricity class 10th science ncert ​

Answer 1

The (a) Option is Incorrect because the Charge  on any material is the integral multiple of the charge on electron which is equal to e = 1.6 x 10⁻¹⁹ Coulomb.

Charge on any material cannot be lesser than this 'e' value.

ie.  Q = ze

where Q = Charge on the material

           z =  Some Integer

           e = 1.6 x 10⁻¹⁹ Coulomb
