Question

. When a charged particle moving with velocity v is subjected to a magnetic field B, when will the force acting on it is non zero?

Answer 1

Answer:

Explanation:

then particle starts to move in circle of radius r = mv/qB , but if speed of particle remains same. so, the energy (i.e., kinetic energy) remains same . consequently, we understand the fact , particle would not gain any energy if it is subjected to magnetic field no matter force acting on it is non - zero.
