Question

In satellite of mass 200 kg in a circular orbit of radius 26000 kilometre around the find the gravitational force between earth and satellite

Answer 1

Answer ⇒ the force will be 76.25 N.

Explanation ⇒

Using the formula,

F = GMeMs/r²

Now,

Me = Mass of Earth

= 6 × 10²⁴ kg.

Mass of the satellite = 200 kg.

Distance(r) = R + h

= 6400 + 26000

= 32400 km = 32400000 m.

Now, Putting these values in the formula,

F = 6.67 × 10⁻¹¹ ×  6 × 10²⁴ × 200/(32400000)²

∴ F = 76.25 N.

Hence, the force will be 76.25 N.

Hope it helps.

Answer 2

Answer:

Explanation:

Me = Mass of Earth

= 6 × 10²⁴ kg.

Mass of the satellite = 200 kg.

Distance(r) = R + h

= 6400 + 26000

= 32400 km = 32400000 m.

Now, Putting these values in the formula,

F = 6.67 × 10⁻¹¹ ×  6 × 10²⁴ × 200/(32400000)²

∴ F = 76.25 N.
