Question

Checking the correctness of physical equations using the method of dimensions is based on A. equality of inertial frame of reference. B. the type of system of units. C. the method of measurement. D. principle of homogeneity of dimensions.

Answer 1

Answer ⇒ Option (d). Principle of homogeneity of dimensions.

Explanation ⇒ Checking the correctness of physical equations using the method of dimensions is based on the Principle of homogeneity of dimensions.

According to the Principle of homogeneity of dimensions, dimensions in each and every terms of the Physical equations are same.

By the Principle of homogeneity of dimensions, Correctness of the Equations can be checked. They are also used for driving some Physical relations.

Hence, Option (d). is correct.
