Question

What would happen if the value of G was twice as large ​

Answer 1

Planetary orbital periods would be affected because the centripetal force would be twice as large. ... And the acceleration of an object with mass m (due to gravity alone) is a_m = F_g/m. Likewise, a_M = F_g / M. The accelerations of the masses would double, if G doubled.

God bless you

Answer 2

Explanation:

Planetary orbital periods would be affected

because the centripetal force would be twice as large. ... And the acceleration of an object with mass m (due to gravity alone) is a_

m = F_g/m.

Likewise, a_M = F_g / M.

The accelerations of the masses would double, if G doubled.
