Question
The electric field at a distance of 20 cm. from the centre of a dielectric sphere of radius 10 cm. is 100 V/m. E at 3 cm. distance from the centre of sphere is :-
Options
A.100 V/m
B.125 V/m
C.120 V/m
D.Zero
Solution
Eout = 
100 =
..........(i)
or KQ = 100 (0.04) = 4
Ein =
= 120
100 =
..........(i)or KQ = 100 (0.04) = 4
Ein =
= 120Create a free account to view solution
