Question

In momentum if the dimension of length and mass are double then new dimension will be? a) Double b) halved c) increase four times d) Ramin same​

Answer 1

Answer:

(a) double

Explanation:

The dimensions of the velocity are Since the length is doubled, there must be no change of time in the velocity to make it double. The dimensions of momentum are MLT−1. As time and mass are constant and the length is doubled, the momentum will be doubled.
