Sliding and Static.
Would be the right one here.
Answer: A person can weigh differently at various place on Earth because of the fluctuations in Earth's gravity, according to a new high-resolution map. ... Earth's gravity is weaker at the equator due to centrifugal forces produced by the planet's rotation

Answer:
Radius of orbit = 3.992 ×
m
Altitude of Satellite =33541.9× m
Explanation:
Formula for gravitational force for a satellite of mass m moving in an orbit of radius r around a planet of mass M is given by;

Where G = Gravitational constant = 6.67408 × 10-11 
We are given
F= 800 N
m = 320 Kg
M = 5.972 ×
Kg
G = 6.67408 × 10-11 
We have to find radius r =?
putting values in formula;
==> 800 =6.67408 ×
× 320 × 5.972 ×
/ 
==> 800= 39.8576 ×
× 320 / 
==> 800 = 12754.43 ×
/ 
==>
= 12754.43 ×
/800
==>
=15.94 ×
==> r = 3.992 ×
m
==> r = 39920×
m
This is the distance of satellite from center of earth. To find altitude we need distance from surface of earth. So we will subtract radius of earth from this number to find altitude.
Radius of earth =6378.1 km = 6378.1 ×
m
Altitude = 39920×
- 6378.1 ×
