Question

If the KE of the body is quadrupled then the momentum of the body doubles.

• A. True
• B. False

Answer 1

The correct option is A True

Kinetic energy of body is given by $K.=\frac{1}{2}m{v}^2$ and momentum is given by $P=mv$

So $P=\sqrt{2mK}$

So if kinetic energy is quadrupled then momentum will be doubled.

So the statement is true.
