What is dimensional Formula of gravity |
|
Answer» F=Gm1×m2÷r×r We know that F = Gm1m2/r^2Now, G=Fr^2/m1m2 (1)Also F= maSo dimensional formula of F = MLT^-2Dimensional formula of r^2= L^2Dimensional formula of m1m2= M^2So 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 |
