Question

Match the following Columns

Answer 1

(A) Any static charge produces electric field invariant with time. Dielectric ring uniformly charged does that here.

(B) Rotating charged behaves like a current.Hence magnetic field is produced around the ring and also if current rotating in a ring, ring has a magnetic moment.

(C) Case is same as that of (B).

(D) Case is same as that of (B), but here current varies with time also. Thus electric field is induced.
