positive charge moving with initial velocity v in a uniform magnetic fieldB experiences a magnetic force F. Which of the following statements is/are ALWAYSTRUE?I. v has no component parallel to F.II. B has no component parallel to v.III. F has no component parallel to B.

The path of a moving charged particle in a magnetic field is ………

Assertion(A): A charged particle is moving in a circular path under the action of auniformmagnetic field. During the motion, kinetic energy of the charged particle isconstant.Reason (R): During the motion, magnetic force acting on the particle is perpendiculartoinstantaneous velocity

A charge particle moving in magnetic field B, has the components of velocity along B as well as perpendicular to B. The path of the charge particle will behelical path with the axis perpendicular to the direction of magnetic field Bhelical path with the axis along magnetic field Bcircular pathstraight along the direction of magnetic field B
