Question

A satellite maintains an orbit equidistant from the earth at all points along its orbital path. How is the satellite affected by the earth's gravity?


A.
The earth's pull of gravity acting on the comet will be reversed over the path of its orbit.


B.
The earth's pull of gravity acting on the satellite remains constant over the path of its orbit.


C.
The earth's pull of gravity acting on the satellite decreases over the path of its orbit.


D.
The earth's pull of gravity acting on the satellite increases over the path of its orbit.

Answer 1

The force due to gravity between 2 bodies is

\[F=\frac{ GMm }{ r^{2} }\]

Where G is universal gravitational CONSTANT
M is the mass of Earth (which doesn't change)
m is the invariant mass of the satellite
and r is the radius of the CIRCLE of orbit

Answer 2

so b?
