A spherical portion has been removed from a solid sphere having a charge distributed uniformly in its volume as shown in the figure. The electric field inisde the emptied space is

A

zero everywhere

B

nonzero and uniform

C

non-uniform

D

zero only at its centre

Text Solution

Verified by Experts

The correct Answer is:
B

`E_(p) = vec(E_(1)) +vec(E_(2))`
`= (rho vec(r_(1)))/(3in_(0)) +((-rho)vec(r_(2)))/(3in_(0))`
`=(rho)/(3in_(0)) (vec(r_(1))-vec(r_(2))) = (rho)/(3in_(0)) vec(a)`
