Question

A body of mass 25kg is displaced from floor to top of table of height 2m . Find its potential energy?
​

Answer 1

To Find :-

• Potential energy of a body.

Solution :-

• Mass of a body (m) = 25 kg

• Acceleration due to gravity (g)= 10 ms-²

• Height (h) = 2 m

Now,

The formula for potential energy is given below,

• PE = mgh

Where,

• PE is the potential energy of the object in Joules.

• m is the mass of the object in kg

• g is the acceleration due to gravity in ms-²

• h is the height of the object with respect to the reference point in m.

[ Put the values ]

$\longrightarrow$ PE = 25 × 10 × 2

$\longrightarrow$ PE = 25 × 20

$\longrightarrow$ PE = 500 Joules

Hence,

The potential energy of a body is 500J.

Answer 2

Answer:

Question

A body of mass 25kg is displaced from floor to top of table of height 2m . Find its potential energy?

Answer.

Potential energy = mgh

Potential energy = 25 × 10 × 2

Potential energy = 25 × 20

Potential energy = 500 Joule
