Question

what is universal gravitational constant

Answer 1

we know that the gravitational force between any two bodies in this universe is directly proportional to the product of their masses and inversely proportional to the square of the distance between them this means to remove the sign of proportionality we need to place there a constant and that constant is called gravitational constant because of applicability In The Whole Universe it is said to be universal gravitational constant and since I have learnt it in in the 9th class at forgotten its value I think it's something like 6.667 into 10 power something which I don't know you can better get the answer from the internet

Answer 2

G is universal gravitational constant it's value is taken as 6.673*10^-11 N m^2 kg^-2
