What are centripital force

A car of mass 1500 kg rounds a curve of radius 250 m at 90 km/h. Calculate the centripetal force acting on it.

An object of mass 50 g moves uniformly along a circular orbit with an angular speed of 5 rad/s. If the linear speed of the particle is 25 m/s, what is the radius of the circle? Calculate the centripetal force acting on the particle.

The ratio of centripetal forces on two clectrons which are revolving around nucleus of hydrogen alom in 2^nd and 3^rd orbits respectively is

IF p is the magnitude of linear momentum of a particle executing a uniform circular motion, then the ratio of centripetal force acting on the particle to its linear momentum is given by
