A light body and a heavy body have the same momentum, which of the two bodies will have greater kinetic energy ?

Text Solution

Verified by Experts

As `E-k = (p^2)/(2m), E_k prop (1)/(m) ("P is the saem for both the bodies")`
Thus, the lighter body has more kinetic enegy then the heavier body through both have the same momentum.

If a light body and a heavy body have equal momentum, then

the lighter body has greater kinetic energy than the heavier body

the lighter body has lesser kinetic energy than the heavier body

the kinetic energy of the lighter body is equal to the kinetic energy of the heavier body

the kinetic energy of both the bodies are independent of momentum

A light and a heavy body have equal momenta. Which one has greater K.E

The light body

The heavy body

The K.E. are equal

Data is incomplete

Assertion : A light body and heavy body have same momentum. Then they also have same kinetic energy. Reason : Kinetic energy does not depend on mass of the body.

If both assertion and reason are true and the reason is the correct explanation of the assertion.

If both assertion and reason are true but reason is not the correct explanation of the assertion.

If assertion is true but reason is false.

If the assertion and reason both are false.
