Question
If a uniformly charged spherical shell of radius 10 cm has a potential V at a point distant 5 cm from its centre, then the potential at a point distant 15 cm from the centre will be :
Options
A.
B.
C.
D.3V
Solution
Potential at 5cm. ⇒ = V = 
(∵ point lying inside the sphere)
Pontential at 15 cm V′ ⇒ V′ =
V.
(∵ point lying inside the sphere)Pontential at 15 cm V′ ⇒ V′ =
V.Create a free account to view solution
