Your answer is ----
Firstly we know about what is centripetal acceleration
• the change of direction of velocity in circular motion is known as centripetal acceleration .
centripetal acc. = v^2/R ......(1)
where ,
v = speed
R = radius
apply Newton second law of motion in circular motion .
Fc = Ma
where ,
Fc = centripetal force
M = mass
a = centripetal acceleration
=> Fc = mv2/R (from 1)
