If a uniformly charged spherical shell of radius 10 cm has a potential V at a point distant 5 cm from its center, then the potential at a point distant 15 cm from the center will be:
A
B
C
D
3V
Text Solution
Verified by ExpertsThe correct answer is:
B
radius of sphere 
at 5 cm from centre, potential is V
point at distance 15 cm from sphere will be on surface of sphere
Potential inside sphere is same as on it's surface
hence 
now V at
