Question

The work done by a force is 400 units. If the units of mass, length and time are doubled, find the numerical value of work​

Answer 1

Answer:

200

Explanation:

We need to find the dimensions of energy.

Energy stored in a system is equal to work done against a force =Fx =max

Hence, the dimensions are [M]×[LT−2]×[L]=[ML2T−2]

Hence, when fundamental units of M,L,T are doubled, the fundamental unit of energy doubles, and hence the magnitude measured in those units halves.
