Question
How would the value of the gravitational constant, G = 6.673
10 - 11 Nm2/kg2 vary if we consider the andromeda galaxy.
- It does not vary at all
- It becomes lesser
- It becomes greater
- Can be lesser or greater but not equal to
Hint:
It is universal.
The correct answer is: It does not vary at all
The correct option is a)It does not vary at all.
The value of the gravitational constant is same everywhere in the universe and is 6.67408 × 10-11 N m2 kg2. The gravitational constant was originally studied by Sir Isaac Newton through the law of universal gravitation.
This was further applied in Einstein's theory of relativity.
This empirical constant is only used to study the effects of gravity in various fields. It is not effected by andromeda galaxy.
