Question

if length force and time are taken as fundamental quantities. what would be the dimensional equation of mass and density...long answer​

Answer 1

Answer:

Let Units of Force, Length and Time are F, L and T respectively.

density = Mass / Volume = (Force/Acceleration)/Volume .................(1)

Acceleration = (Change of velocity ) / Time = (distance /Time) /Time ..............(2)

from eqn.(2), we can write uint of acceleration = L / T2 ....................(3)

hence using unit of acceleration and using eqn.(1), unit of mass
