Question

What are central forces ? Give some examples of such forces?

Answer 1

Answer:

A central force is a force (possibly negative) that points from the particle directly towards a fixed point in space, the center, and whose magnitude only depends on the distance of the object to the center.

Two familiar examples for central force are the gravitational force and Coulomb force with F(r) being proportional to 1/r2. For an object with such a force where F(r) is negative obeys Kepler's laws of planetary motion.

Answer 2

Answer:

Explanation:

central forces are the forces which act along the lines joining the centre of mass of the two matter
