Answer:

Explanation:
We are given that
Mass of spherical shell,
=1900 kg
Mass=
Radius of shell=r=5 m
Distance between two masses=r=5.01 m
Because distance measure from center .
Gravitational force


Using the formula


Hence,the gravitational force =
Tha atmosphere has no effect on gravity.
It is probably transversal.
The particles vibrate perpendicular to the direction of an energy transmission.
