Question

Using principle of homogeneity rule out the wrong formula for kinetic energy of a body.



E = ½MV²

E = Ma

E = 3/16 MV²

E = 2/5 Mc²

​

Answer 1

The principle of homogeneity states that the dimensions of each the terms of a dimensional equation on both sides are the same. Using this principle the given equation will have same dimension on both sides. Thus, the dimension on both sides quantities are same.
