hope it help

make me brainliest

Answer 2

Please refer to the attachment above for the derivation and proof.

●In this sum I have used Dimensional Analysis to come to the desired result. For this i have used the dimensional formula.

Q1.What is a dimensional formula?

answer ➡️ It is the expression which shows that which of the base quantities represent the dimensions of a given physical quantity. Through this we arrive finally at a dimensional equation of the physical quantity. The whole process thus used to prove the result is called the principle of Homogeneity of Dimensions and helps in checking the correctness of an equation.
