Question

if the relation has the same dimensional formula , this means the the equation is true ?

Answer 1

Answer:

The dimension of a physical quantity is defined as the power to which the fundamental quantities are raised to express the physical quantity. The dimension of mass, length and time are represented as [M], [L] and [T] respectively.

The dimensional formula is defined as the expression of the physical quantity in terms of its basic unit with proper dimensions.

Dimension formula of a physical quantity can only be written when its relation with other physical quantities is known.

Answer 2

Answer:

The dimension of a physical quantity is defined as the power to which the fundamental quantities are raised to express the physical quantity. The dimension of mass, length and time are represented as [M], [L] and [T]respectively. For example:



We say that dimension of velocity are, zero in mass, 1 in length and -1 in time.

Dimensional formula of a Physical Quantity

The dimensional formula is defined as the expression of the physical quantity in terms of its basic unit with proper dimensions. For example, dimensional force is

F = [M L T-2]

It's because the unit of Force is Netwon or kg*m/s2
