Answer:
The horizontal applied force is 150.67 N.
Explanation:
We have,
Distance covered by the applied force on the couch is 0.75 m
Work done by the couch is 113 J
It is required to find the magnitude of the horizontal force applied. Due to the application of force work is done by an object. It can be given by :
F is horizontal force applied
So, the horizontal applied force is 150.67 N.

The gravitational force between two objects is given by:
where
G is the gravitational constant
m1 and m2 are the masses of the two objects
r is the separation between the two objects
The distance of the telescope from the Earth's center is
, the gravitational force is 
and the mass of the Earth is 
, therefore we can rearrange the previous equation to find m2, the mass of the telescope:
where
G is the gravitational constant
m1 and m2 are the masses of the two objects
r is the separation between the two objects
The distance of the telescope from the Earth's center is
