Question

# What is the dimensional formula of moment of force?

Solution

## We have unit of mass as Kg dimensions are $$[M^1][L^0][T^0]$$  unit of acceleration as $$m/s^ 2$$  dimensionally expressed as $$[M^0][L^1][T^{−2}]$$ hence we have unit of force as $$Kg\times m/s^2$$So dimensionally it can be written as $$[M^1][L^0][T^0]\times[M^0][L^1][T^0][M^0][L^0][T^2] = Kg\times ms^2$$Hence we get dimensional formula as  $$[M^1][L^1][T^{−2}]$$Physics
