Correct Answer: M ^-1 L ³ T ^-2

Solution : The correct answer is M ^-1 L ³ T ^-2 .

Gravitational Constant was given by Sir Issac Newton. It is a proportionality constant which is the value of the gravitational force acting between the two bodies of unit mass and which are kept at a unit distance from each other. It is denoted as capital G. Its value was calculated by Sir Issac Newton which was equal to 6.674 x 10 ^-11 Nm ² / kg ² . It has a dimensional formula M ^-1 L ³ T ^-2 .
