The point charge is placed outside a spherical shell as shown i the figure. Find the electric potential (in kilo volt) on the surface of shell (Take: `q=1 mu c` and `R=50cm`)

Text Solution

Verified by Experts

The correct Answer is:
9
`[9]`
Field inside the shell is zero, so potential is uniform
`V=(kq)/(2R)=9` kilo volts
