## Work done by a variable force.

Suppose a variable force acts on a body along the fixed direction, say x-axis. The magnitude of the force depends…

## The potential energy in relation to conservative force.

When the conservative force (for simplicity, in one dimension) does work on a particle within the system, the change in…

## The circular motion of a can on a banked road.

Consider a car of weight going along a curved path of radius with speed on a road banked at an…

## Pulling a lawn roller is easier than to push it.

It is easier to pull a body than to push it. Suppose a force is applied to pull a lawn…

## Magnetc field due to toroid using Ampereâ€™s circuital Law

A toroid is an endless ring shaped solenoid.Consider a toroid having n turns per unit length through which current i…

## Bending of a cyclist.

When a cyclist rounds a curved path, a centripetal force is required. The force of friction between the tyres and…
