An electron of mass 'm' moves with a uniform speed v around the nucleus along a circular radius 'r'. Derive an expression for the acceleration of the electron.

A person drives a car along a circular track on a level ground. Derive an expression for the maximum safe speed of the car.

Does the velocity of an object moving with a uniform speed along a circular path change ?

According to Bohr atom model electrons are revolving in circular orbits around the nucleus. The movement of electrons can be regarded as a circular current flow. Then derive an expression for the magnetic dipole moment of an orbital electron.

A hydrogen ion of mass 'm' charge 'q' travel with a speed 'v' along a circle of radius 'r' in uniform magnetic field of flux density 'B". Obtain an expression for the magnetic force on the ion and determine its time period?

An electron moves under a potential difference of 300V. Derive an expression for Its wave in terms of charge of particle.
