A particle is projected from a point of an angle with the horizontal. At any instant t, if p is the linear momentum and E the kinetic energy, then which of the following graph is/are correct?

A

B

C

D

Text Solution

Verified by Experts

The correct Answer is:
D
`p^(2) = 2Em` or `p^(2) alpha E`
i.e., `p^(21)` versus E graph is a straight line passing through origin.
