Show that the kinetic energy of the particle moving in a magnetic field remains constant

Answer the following: (a) Write the expression for the force vec(F) acting on a particle of mass m and charge q moving with velocity vecV in a magnetic field vecB . Under what conditions will it move in (i) a circular path and (ii) a helical path ? (b) Show that the kinetic energy of the particle moving a magnetic field remains constant.

Establish analytically that the gain in kinetic energy of the charged particle moving in a magnetic field is zero.

A proton and an alpha particle of the same velocity enter in turn a region of unifrom magnetic field acting a plane perpendicular to the magnetic field. Deduce the ratio of the radii of the circular paths described by the particles. Explain why kinetic energy of the particle after emerging from the magnetic field remains unaltered.

The change in the kinetic energy of a charged particle moving in a uniform magnetic field will be zero when its velocity is

The change in the kinetic energy of a charged particle moving in a uniform magnetic field will be zero when its velocity is

When a charged particle moves in a magnetic field, does its KE always remain constant?

A particle is moving in a uniform magnetic field, then

(A) : The energy of charged particle moving in a uniform magnetic field does not change. (R) : Work done by magnetic field on the charge is zero.
