Question
a point charge q is placed at a distance 2r from the centre O of a conducting charged sphere of radius r. due to induced charges on the sphere , find the elecric potential at point P on the surface of sphere in volt if kq/r =18V.
in the above ques, last time u found out potential at center but according to ques we hav eto find out on the surface and ans. is 3
Joshi sir comment
if the answer is 3 V then 2r should be the distance of q from surface not from centre.
first confirm

for conducting shell potential at centre is equal to the potential at surface. As potental is asked due to +q induced charge & due to -q induced charge thus potential due to induced charges will be 0,
