Question: At a point 20 cm from the centre of a uniformly charged dielectric sphere of radius 10 cm, the electric field is 100 V/m. The electric field at 3 cm from the centre of the sphere will be [BCECE 2005]
Options:
A) 150 V/m
B) 125 V/m
C) 120 V/m
D) Zero
Show Answer
Answer:
Correct Answer: C
Solution:
Electric field outside of the sphere
Electric field inside the dielectric sphere
From (i) and (ii),
