Answer 2

hey mate here is ur answer

You don't need to memories the dimensional formula.

They can never be learnt just by memorizing one by one .

You have to know the dimensional formula for fundamental units only with lenght, time, mass.

to find the dimentional formula of a quantity go for the basic formula of the quantity in terms of fundamental units .

example

dimensional formula of surface tension

surface tentions is simply force per unit length.

T=F/L

F=MLT-2

T=MLT-2/L=MT-2

hope this much answer is enough for u if not then may ask from others.
