Question

Two objects, A and B, are 10 m apart. Objects C and D are 20 m apart. The gravitational attraction between objects C and D is greater than the attraction between objects A and B. Explain the reason for the difference in gravitational attraction.

A. The combined mass of objects C and D must be greater than the combined mass of objects A and B.
B. Objects A and B are larger than objects C and D.
C. The weight of objects C and D is greater than objects A and B

(hhhheeellllppp)

Answer 1

Answer:

Gravity=Gm1m2/r2

in 1st case r is less and in 2nd case r is large but

as per Q . 2nd one have higher G its reason is their masses are large.Therefore option A.
