Question

If force f,length l and time t would be considered as fundamental units.find dimensions of mass.
A)fv^-1
B)Ev^-2
C)none

Answer 1

Answer: Option b). E v^-2

Explanation:

E= kg*m^2* s^-2

v= m*s^-1

kg = E*v^-2

= kg*m^2* s^-2 *(m*s^-1)^-2

=kg(m^2* s^-2 *m^-2* s^2) ......()=m^0s^0 kg= kg^1

But check with the que. as the option should be in terms of f,l & m
