Question

What is the centripetal acceleration of the ball if its mass is doubled?

• A. a/4
• B. a/2
• C. a
• D. 2a
• E. 4a

Answer 1

The correct option is C a

Initial centripetal acceleration $a=\frac{v^2}{r}$

$⟹$ Centripetal acceleration is independent of mass of the ball.

Hence new centripetal acceleration $a^{\prime }=a$
