Question

A negatively charged particle initially at rest is placed in a magnetic field that varies from point to point. Neglect the effect of all other fields, then:
a)The particle moves along the magnetic field lines passing through the point
b) The direction of acceleration of the particle is tangential to the magnetic field lines at every instant
c) The charge remains at rest
d) Work done by magnetic force increases the kinetic energy of the particle

Answer 1

option C is the right answer
