Q1.11Multiple correct
Consider a region inside which there are various types of charges but the total charge is zero. At points outside the region
- (a)the electric field is necessarily zero.
- (b)the electric field is due to the dipole moment of the charge distribution only.
- (c)the dominant electric field is ∝ 1 , for large r, where r is the r3 distance from a origin in this region. Gaussian surface
- (d)the work done to move a charged particle along a closed path, away from the region, will be zero.
