F=Gm1×m2÷r×r

Divyanshu Mallik 5 years, 11 months ago

We know that F = Gm1m2/r^2 Now, G=Fr^2/m1m2 (1) Also F= ma So dimensional formula of F = MLT^-2 Dimensional formula of r^2= L^2 Dimensional formula of m1m2= M^2 So Dimensional formula of G= MLT^-2*L^2/M^2 (from1) On solving this we get the dimensional formula of G as, G=M^-1 L^3 T^-2
