Concept explainers
The gravitational force with which each galaxy attracts each other.
Given:
The nearest large galaxy is about
Both galaxies have mass of
Formula used:
Here, m1 and m2 are masses.
r is the distance between the two masses.
G is gravitational constant
Calculation:
1 light year =
So,
G is equal to
