Question

Define the dimension and dimension formula 1 gravitation (constant)2 pressre

Answer 1

Dimension

A measurable extent of particular kind, such as length, breadth , depth or height.

or

A power to which the fundamental quantity are raised to the expess of the physical quantity

Formula

F =(M L T - 2)

I don't know the gravitational to pressure sorry

Answer 2

$\Large{\underline{\underline{\bf{Solution :}}}}$

★ Dimensional Formula of Gravitational constant (G)

We know that,

$\Large{\implies{\boxed{\boxed{\sf{G = \frac{G \: m_1 \: m_2}{r^2}}}}}} \\ \\ \sf{→G = \frac{F \: r^2}{m_1 \: m_2}} \\ \\ \sf{→G = \frac{M^1 L^3 T^{-2}}{M^2}} \\ \\ \sf{→G = M^{-1} L^3 T^{-2}}$

$\rule{200}{2}$

★ Dimensional formula of pressure

We know that,

$\Large{\implies{\boxed{\boxed{\sf{Pressure = \frac{Force}{Area}}}}}} \\ \\ \sf{→Pressure = \frac{M^1 L^1 T^{-2}}{L^2}} \\ \\ \sf{→Pressure = M^1 L^{-1} T^{-2}} \\ \\ \Large{\implies{\boxed{\boxed{\sf{Pressure = M^1 L^{-1} T^{-2}}}}}}$
