Question

a body has charge 6.4×10^-8 calculate no. of electrons removed​

Answer 1

Answer:

The No. of Electrons are 40*10¹⁰ electrons or, 4.0*10¹¹ electrons.

Explanation:

Given,

Electric Charge = 6.4*10⁻⁸ C

∴No. Of Electrons = 1 C = 6.25*10¹⁸ electrons

= 6.4*10⁻⁸ C = [6.4*6.25] * 10¹⁸⁺⁽⁻⁸⁾

= 40*10¹⁰ electrons

Or,

= 4.0*10¹¹ electrons

Hope this helps.
