Question

b) Calculate the potential energy of body of mass 10 kg at a mass at a height of 10​

Answer 1

Answer:

Potential energy of the body = mgh.

Mass of body = 10 kg.

Height above the earth = 6 m.

Acceleration due to gravity = 10 m/s2

So, EP = 10 × 10 × 6 = 600 J.

Thus, potential energy of the body is 600 Joules.

Answer 2

Correct Question :

Calculate the potential energy of body of mass 10 kg at the height of 10.

Provided Information :

• Mass of an Object = 10 kg
• Height above the ground = 10 m
• Gravitational force = 10 m/s²

What we have to do ?

We will apply the formula for potential energy which is the product of mass of Object , height and gravitational force.

Formula Used :

The potential energy of a body is due to its higher positions above the earth and it is equal to the work done on the body, against gravity, in moving the body to that position.

${\boxed{\sf{ Potential \: Energy = Mass \times Gravational \: Force \times Height}}}$

Let's do it now :

$\dashrightarrow\:\: \sf m \times g \times h$

Here,

• m = mass of the body.
• g = Acceleration due to gravity.
• h = height of the body above a reference point, say the surface of earth.

$\dashrightarrow\:\: \sf Potential \: energy = 10 \times 10 \times 10$

$\dashrightarrow\:\: \sf Potential \: energy = 100 \times 10$

$\dashrightarrow\:\: \sf Potential \: energy = 1000$

$\dashrightarrow\:\: \underline{ \boxed{\sf Potential \: energy = 1000 J }}$
