Assertion : Power of a constant force is also constant.
Reason : Net constant force will always produce a constant acceleration.

Options

A. If both Assertion and Reason are true and the Reason is correct explanation of the Assertion.
B. If both Assertion and Reason are true and the Reason is not the correct explanation of the Assertion.
C. If Assertion is true, but the Reason is false
D. If Assertion is false but the Reason is true.

Answer

D

Explanation

`F = "constant"`
`:. a = (F)/(m) = "constant"`
`v = at = (F)/(m) t`
`P = F.v = (F^(2))/(m)t`
`P = f.v=(F^(2))/(m)t`
`:. P ne "constant"`
But `P prop t`
