Question

1. state the value of G.who obtained it for the first time??
2. which force is responsible for motion of moon around the earth ?? what would happen if
there was no such force ??
frnds plz help ​

Answer 1

Answer:

1.The constant of proportionality in this equation is G - the universal gravitation constant. The value of G was not experimentally determined until nearly a century later (1798) by Lord Henry Cavendish using a torsion balance.

2.Newton called this force gravity and is a force of universal attraction that acts distantly, connecting the Moon with the Earth. Thus the centrifugal force due to the movement of the Moon around the Earth is counteracted by the force of gravity.

Hope it will help you

Answer 2

Answer:

The Cavendish has performed an experiment to calculate the gravitation force between two masses. and he gave the value of gravitational constant G, which is equal to 6.75×10−11  Nm2kg−2
