Explain the Concept of Centripetal Force. - HSC Science (General) 12th Board Exam - Physics

ConceptDynamics of Uniform Circular Motion - Centripetal Force

Question

Explain the concept of centripetal force.

Solution

a.   Force acting on a particle performing circular motion along the radius of circle and directed towards the centre of the circle is called centripetal force.
It is given by FCP =(mV^2)/r
where, r = radius of circular path.
b.   Example: Electron revolves around the nucleus of an atom. The necessary centripetal force is provided by electrostatic force of attraction between positively charged nucleus and negatively charged electron.
c.   Unit: N in SI system and dyne in CGS system.
d.   Dimensions: [M^1L^1T^-2]
