Question

what is G value and why is it that so​

Answer 1

Answer:

Its value is 9.8 m/s2 on Earth. That is to say, the acceleration of gravity on the surface of the earth at sea level is 9.8 m/s2. When discussing the acceleration of gravity, it was mentioned that the value of g is dependent upon location. G is constant.The value of G is 6.67×10–11 m2 kg-2.

Explanation:

Answer 2

Answer: "G" is the universal gravitational constant whose value is 6.673×10^-11 Nm^2 kg^-2 which is equal everywhere

Explanation:

since, according to Newton's universal law of gravitation

"F" is directly proportional to product of masses of two objects and inversely proportional to square of distance.

Which is F=G*m1*m2÷d^2

here "G" is the proportionality constant. Its experimentally measured by "Henry Cavendish" and its SI unit can be found as given in the attachment.
