a p.d = V is applied between two long coaxial coducting pipes of radii 'a' and 'b' with b > a , with the inner pipe at lower potential . uniform magnetic field of magnitude B exists in the region, parallel to the length of the pipes.an electron leaves the surface of the inner pipe with negligible velocity.find the values of B for which the electron can't reach the outer pipe.
