Question

Find the force needed to keep a mass m in a circular path of radius r with period t.

Answer 1

Explanation: for circular motion centripetal force is involves

as we know, F= mass× acceleration

F= mv²/ r

r = radius

v = 2πr/ t

here t = time and v = velocity/ speed

as we know v= d/ t= 2πr/t

therefore F = m×(2πr/t)²/r
