Write dimensional formula of universal constant of gravitation (G).

1.	Write dimensional formula of universal constant of gravitation (G).
Answer» `MLT` `M^(-1) L T^2` `M^0 L^0 T^0` `M^(-1) L^(3) T^(-2)` Solution :`implies F=G(m_1m_2)/(r^2) implies G =(Fr^2)/(m_1m_2)` `[G] = ([F][r^2])/([m_1] [m_2] ) = (M^(1) T^(-2) xxL^(2))/(M^(1) xxM^(1))` `[G] = M^(-1) L^(-3) T^(-2)`
