Question

A particle moves in a circular path of radius 10 cm with constant speed of 10 cm/s. Its acceleration is

Answer 1

Explanation:

radius =10cm=10/100=0.1m

speed=10cm/s=o.1m/s

Since the particle is moving in a circular path of radius 10 cm, with a constant speed of 10 cm/s, the acceleration it is experiencing is the centripetal acceleration of magnitude | a | = v²/r, where v= 10 cm/s, is the constant speed in the circular path, and r is the radius of the path.

| a |= 10²( cm²/s²)/ 10 (cm/s)= 10 cm/s².

The acceleration has a magnitude of 10 cm/s² directed from the particle to the centre of the circular path.
