Question

In a system force velocity and energy is taken as base unit what is dimension of mass in new system of unit

Answer 1

let the dimensional formula of mass is M = EaFbVc

E=ML2T-2 , F =MLT-2 , V=LT-1

on putting these

M = Ma+b L2a+b+c T-2a-2b-c

equating powers ,we get

a=1 , b=0, c=-2

dimensional formula of mass= E1.F0 V-2
