Gauss LawMedium
Question
Electric charges are distributed in a small volume. The flux of the electric field through a spherical surface of radius 20cm surrounding the total charge is 50 V-m. The flux over a concentric sphere of radius 40 cm will be:
Options
A.50 V-m
B.75 V-m
C.100 V-m
D.200 V-m
Solution
since same no of field lines are passing through both spherical surfaces, so flux has same value for both.
