Question

If length L ,force F and time T are taken as fundamental quantities then what would be dimensional equation of mass?

Answer 1

Answer: M = F/a

F= FORCE

a= ACCELERATION

Explanation:

M = LFT

[M] =[L]power a [F] power b [T]power c

so L has no dimension in LHS

so  a = 0 and also c=0

  dimensional formula of force is MLT power-2

here [M] depends only on [F]

so equation of force = ma (where m is mass and a is acceleration)

  so dimensionally correct equation for mass = f/a
