Question

if both speed of a body and radius of its circular path is doubled what will happen to centripetal acceleration​

Answer 1

Explanation:

Centripetal acceleration= v²/r

If speed of body get doubled then new speed is 2(v²)

If radius of body get doubled then new radius 2r

New centripetal acceleration=2v²/2r = v²/r

Thus, original centripetal acceleration= new centripetal acceleration Answer
