Answer 1

Explanation:

The number of electrons to be put on a spherical conductor of radius 0.1m to produce an electric field of 0.036N//C just above its surface is. =2.5×105.

Answer 2

Given:

The number of electrons to be removed from A spherical conductor of radius 0.1 m to produce an electric field of 0.036 N/C on its surface is

Solution:

$for \: a \: sherical \: conclustor \\ e \: = \frac{kq}{ {r}^{2} } \\ 0.03( = \frac{9 \times {10}^{9} \times 4 \times 1.6 \times {10}^{ - 19} }{0.01}) \\ = > \: n \: = \: 2.1 \: \times \: 105$
