A particle is moving under the influence of a force which is fixed in magnitude and acting at an angle `theta` in the direction of motion. The path described by the particle is

The path of a particle moving under the influence of a force fixed in magnitude and direction is [

A particle moves in x-y plane in figure under the influence of a friction force with magnitude 3.00N and acting in the direction opposite to the particle's displacement. Calculate the work done by the friction force on particle as it moves along the following closed paths: (a) path OA followed by AC and return path AO, (b) path OA followed by AC and the return path CO, (c) path OC followed by the return path CO, and (d) each of your three answers should be non-zero. What is the significant of this observation?

A charged particle q is moving in the presence of a magnetic field B which is inclined to an angle 30° with the direction of the motion of the particle. Draw the trajectory followed by the particle in the presence of the field and explain how the particle describes this path.

In which direction of the motion of the particle does centripetal force act ?

Discuss the motion of a charged particle in a uniform magnetic field, when it moves at an angle theta with the direction of magnetic field. Prove that the path is helical.

Show that a system of particles moving under the influence of an external force, moves as if the force is applied at its centre of mass.
