When a charged particle moving with velocity v is subjected to a magnetic field of induction B , the force on it is non-zero. This implies that

Options

  1. Aangle between v and B is necessarily 90^
  2. Bangle between v and B can have any value other than 90^
  3. Cangle between v and B can have any value other than zero and 180^
  4. Dangle between v and B is either zero or 180^

Correct answer

C. angle between v and B can have any value other than zero and 180^

Step-by-step solution

When a charged particle q is moving in a uniform magnetic field B with velocity v such that angle between v and B be , then due to interaction between the magnetic field produced due to moving charge and magnetic force applied, the charge q experiences a force which is given by F=q v B If =0^ or 180^ , then =0 F=q v B =0 Since, force on charged particle is non-zero, so angle between v and B can have any value other than zero and 180^ . Note : Force experienced by the charged particle is Lorentz force.
