The mathematical,expression for Universal Law of GRAVITATION is given F=G \'frac{m_{1} m_{2}}{d^2' a) Who formulate this làw? b) What does G stand in this equation? What is its value? Name the scientist who determined the value of G for the first time. c).Two objects are kept at certain distance. How many times will the GRAVITATIONal force between them be if the mass of both bodies are doubled? d). What if the distance between them is doubled.

Explanation

a) Sir Isac Newton
b) GRAVITATIONal constant, .G=6.67 times 10^(-1) Nm^(2) kg^(-2).
Henry Cavendish
c) GRAVITATIONal force will be increased to four times.
d) The GRAVITATIONal foce becomes 1 /4 th
