Question

i). State whether following statement is true or false The value of 'G'changes from place to place
​

Answer 1

Answer:

Explanation:

False because

It is a gravitational constant

Answer 2

✴Answer:-

False

________________________________

✴Reason:-

The value of G does not change from place to place. It is a universal constant. The gravitational constant is the constant of proportionality in Universal Gravitation law given by Issac Newton and is commonly denoted by 'G'. This is different from 'g', which denotes the acceleration due to gravity.

________________________________

✴More To Know:-

• In every place of both Earth and the universe, the value of G remains constant. The value of G does not change with a change in the height, and depth from the earth's surface.

• The first direct measurement of gravitational attraction between two bodies in the laboratory was performed in 1798, seventy-one years after Newton's death, by Henry Cavendish. He determined a value for G implicitly, using a torsion balance invented by the geologist Rev. John Michell (1753).

• The acceleration due to gravity on the surface of the Moon is approximately 1.625 m/s2, about 16.6% that on Earth's surface or 0.166 ɡ.
