Assertion: 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 the same but not zero.

Reason: The whole pipe can be supposed to be made of thin rings. The magnetic field on the axis of the ring is $\frac{μ_{0} i}{2 a}$ . So, the total field is not zero.

Both assertion and reason are true and reason is correct explanation of the assertion.

Assertion: A proton and an $α$ - particle are projected with the same kinetic energy at right angle to a uniform magnetic field, then the $α$ - particle will move along a circular path of smaller radius than the proton.

Reason : $B q v = \frac{m v^{2}}{r}$ holds good for the charged particle moving in a circular path in a uniform magnetic field.
