Question

a charged particle q is moving with speed v perpendicular to the magnetic induction field b, then find the radius of the path and time period of particle​

Answer 1

Answer:

The radius of charged particle q (mass=m), moving with velocity v, perpendicular to magnetic field B is given by,

r=mv/qB

r=mv/q

as new particle has same mass, same charge and same velocity v, therefore radius r will be same for new particle,

now if new particle has charge - q, then by Fleming's left hand rule, it will experience a force in the opposite direction as experienced by charge q, therefore path of new particle will be counter-clockwise.
