Question

(Prepar
1. Deduce the dimensional formula for the following physical quantities:
(a) Gravitational constant​

Answer 1

Explanation:

★ WE KNOW,,

F=(Gm1m2)/r² (Where,G is gravitational constant)

Therefore,,

G=(Fr²)/(m1m2)

=>[G] = [F][r²]/[m1m2]

=>[G] = [MLT-2][L2]/[M2]

=>[G] = [M-1 L3 T-2]

HENCE,, Dimensional Formula of gravitational constant G is given by [M-1 L3 T-2]...
