Question

Four satellites are in orbit around the Earth. The heights and the masses of
the four satellites are given in the table. For which satellite is the gravitational
pull of Earth the strongest?F= Gm1m2/r^2
A. Satellite A
B. Satellite B
C. Satellite C
D. Satellite D

Answer 1

Answer:

satellite B

Explanation:

A .F= G (mM)/r²

B .F= G (2mM)/r² = 2G (Mm)r²

C .F= G (3mM)/(2r)² = ¾G (mM)/r²

D .F= G (4mM)/(2r)² = G (mM)/r²
