Question

if the units of force energy and velocity in new system be 10N , 5j and 0.5 ms/s respectively find the unit of mass length and time in that system

Answer 1

Explanation:

Force=[M1L1T−2]=F

Energy=[M1L2T−2]=E

Velocity=[LT−1]=V

M1αFaEbVc

M′=(M1L1T−2)a(M1L2T−2)b(LT−1)c

1=a+b:b+c=−1:c=−2

0=a+2b+c:−(2a+2b)−
