Question

What do you understand by dimension of physical quantity?

Answer 1

Answer:

Explanation:

Dimensions of a physical quantity relates any quantity with the fundamental quantities of mass (kg), length (m) and time (s). We can denote any derived quantity in the dimensional form using these fundamental or base quantities.

M L T raised to the power of the final derived formula.

Answer 2

Answer:

Explanation:dimensions of physical quantity means getting MLT ( mass, length and time) on the basis of the unit of any physical quantity

For eg. : what is dimensions of force?

Ans: the unit of force is Newton (N) or kg m / s^2 , therefore here mass = kg, length = meter and time= sec ^2

Theredore its dimension = M^1 L^1 T^-2 ( as sec is in denominator, it will get - sign)
