Question

The number of electrons to be put on a spherical conductor of radius 0.1m to produce an electric field of 0.036 n/c just above its surface is

Answer 1

$25 \times {10}^{4}$

Explanation:

I'm not sure about the answer as I am travelling and solved it in my mind. But I can guide you through the process.

E = Kq / r^2

You have the value for E = 0.036 N/C

you have the value for r , as , 0.1m

you have the value of K as 9 x 10^9.

Placing the value in the expression , you get q = 0.4 x 10^(-13 )

Now you must be remembering the formula q=ne

e = 1.6x10^(-19)

solving for n from given equation gives

n= 25x10^4
