  • 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

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

Answers (1)

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
