If the unit of length is doubled unit of time is halved and unit of force is quadrupled the unit of power would change by the factor

S safeer

Unit of power = unit of force x velocity= unit of force x unit of (length/time)

Let P= F (l/t)

Given length becomes double that is 2l

time become half, that is t/2

and force becomes 4F

Therefore power P'=4F(2l/(t/2))

P'=16 F(l/t)=16P
