Question

A body of mass m=20kg is placed atA. Find the gravitational potential at a distance of 40m at B.

Answer 1

Answer:

ye to batao ki distance vertical hai ya horizantal

Answer 2

Given

A body of mass 20 kg is placed at a height of 40 m from earth

To Find

Potential Energy

Solution

We know that

$\sf \longrightarrow PE=mgh$

Here

• PE = Potential Energy
• m = Mass
• g = Acceleration of gravity
• h = Height

According to the question

We are asked to find potential energy

Therefore

We must find "PE"

Given that

A body of mass 20 kg is placed at a height of 40 m from earth

Hence

• m = 20 kg
• h = 40 m

We know that

g = 10 m/s²

Substituting the values

We get

J⟶PE=20×10×40 J

Therefore

$\sf \longrightarrow PE=8000 \ J⟶PE=8000 J$

Hence

Potential Energy = 8000 J
