A current I flows along the lenght of an infinetely long, straight, thin walled pipe. Then

(A) : A current I flows along the length of an infinitely long, straight, thin-walled pipe. Then the magnetic field at all points inside the pipe is zero. (R) : The whole pipe carrying current can be supposed to be made of thin rings. The magnetic field on the axis of the ring is is zero.

A current I flows along the length of an infinitely long, straight , thin - walled pipe. Then

A current i flows along the length of an infinitely long, straight, thin-walled pipe. Then, (a) the magnetic field at all points inside the pipe is the same, but not zero (b) the magnetic field at any point inside the pipe is zero (c) the magnetic field is zero only on the axis of the pipe (d) the magnetic field is different at different points inside the pipe
