Linear momentum of a particle given by relation `p = a + b t^(2)`, where a, b are constant and t is time, then force acting on particle is ………..

A

propotional to t

B

propotional to `t^(2)`

C

zero

D

constant

Text Solution

Verified by Experts

The correct Answer is:
A
`p=a + bt^(2)`
`:. , (dp )/( d t) = 0 + 2bt `
`F = 2 bt , 2b = ` constant
`F prop t`
