Question

If the unit of mass and length be doubled and that of time is halved,then how the unit of force, work and power is affected

Answer 1

F=ma
if m is doubled than
F'=2ma
P=W÷t
W=F.d
so
P=F.d÷t
P'=2F.d÷1÷2t (as time is halved)
P'=4 F.d÷t (the 2 that is in division will move up and will multiply with 2 of F)
so P'=4P


but their is no change on units
hope it helps u
