Question

a body is moving along a circle with an increasing speed is a possesses
(a) centripetal acceleration only (ac)
(b) tangential acceleration (ar)
(c) both tenge tial and centripetal acceleration ( ar and ac)​

Answer 1

Answer:

If a body is moving with increasing velocity on a circular path, it possesses both tangential and centripetal acceleration.

If velocity is constant, it possesses centripetal acceleration.

Answer 2

Both centripetal and tangential acceleration present.

• Let's assume that a body is moving along a circular trajectory with increasing speed.

• That means the linear velocity is increasing with time. So, the object will have linear or tangential acceleration.

• Centripetal acceleration = v²/R , so with increase in velocity (v) , the centripetal acceleration will also increase.

• So, body will also have centripetal acceleration.

Hence, both a_(c) and a_(r) will be present
