A) 20 V
B) 60 V
C) 80 V
D) 40 V
Correct Answer: D
Solution :
If charge acquired by the smaller sphere is Q then it?s potential \[120=\frac{kQ}{2}\] ..... (i) Also potential of the outer sphere \[V=\frac{kQ}{6}\] .....(ii) From equation (i) and (ii) V = 40 voltYou need to login to perform this action.
