Here, we will find out the dimensional formula of force.
The formula of force = mass x acceleration
The dimension of mass = [M]
The dimensional formula of acceleration = [M0LT–2] [see here how to find the dimensional formula of acceleration ]
Hence, the Dimensional formula of force
= The dimension of mass x The dimension of acceleration
= [M] [M0LT–2]
Dimensional formula of force = [MLT–2]
