Question

How does the force of gravity change between two planets when the masses ofBOTH planets are doubled?

Fg=G m1m2
d2
O A
2 times the gravity
B.
4 times the gravity
O
C
no change in gravity
Oo
1/2 the gravity

Answer 1

B. 4 times

Step-by-step explanation:

Fg'=G(2m1)(2m2)/d²

Fg'=4Gm1m2/r²
