Question

A charge of 2 uC is uniformly distributed on a
spherical shell of radius 5 m. Electric potential at
the centre of sphere is
Zero
4.5 x 103 v
7.2 x 103 v
3.6 % 103 v​

Answer 1

Answer:

V= kq/r

= 9*10^9*2*10^-6/5

= 3.6*10^ 3

Answer 2

Answer:

3.7*103V

Explanation:

concept: potential at the centre of sphere=kq/r

given: charge ,q=2uC=2*10^-6

radius=5m

find : potential at the centre of sphere

explanation:

potential at the centre of sphere=kq/r

kq/r= 9*10^9 * 2*10^-6/5

V=3.6*10^3
