An electron gun is placed inside a long solenoid of radius R on its exis. The solenoid has n turns/Length and carries a current I. The electron gun schoots an electron along the radius of the solenoid with speed v.If the electron does not hit the surface of the solenoid, maximum possible value of v is (all symbols have their standard meaning):
