Consider a uniform spherical charge distribution of radius R 1 centered at the origin O. In this distribution, a spherical cavity of radius R 2 , centered at P with distance OP = a = R 1 – R 2 (see figure) is made. If the electric field inside the cavity at position 
is 
, then the correct statement(s) is(are)
A
is uniform, its magnitude is independent of R 2 but its direction depends on 
B
is uniform, its magnitude depends on R 2 and its direction depends on 
C
is uniform, its magnitude is independent of a but its direction depends on 
D
is uniform, and both its magnitude and direction depends on 
Text Solution
Verified by ExpertsThe correct answer is:
D
Here, total electric field 
Hence 
is uniform and botyh its magnitude and direction depend on 
.
