Question

A body of mass 50000 GM's is lefted 30m above the ground. Calculate the potential energy of the body. (Given g=10m/s square)

Answer 1

Answer:

15000J

Explanation:

Given:

Mass(m)=50000gm=50000/1000kg=50kg

g=10m/s square

Height (h)=30m

Potential Energy (P.E)=mgh=50×10×30J=15000J.

Answer 2

Given:

• Mass , m = 50000 gram

• Height above the ground,h = 30 m

• Acceleration due to gravity,g = 10 m/s²

To be calculated:

Calculate the potential energy of the body?

Formula used:

Potential energy = m × g × h

Solution:

We convert 50000 grams into kilograms.

We know that,

1 kg = 1000 grams

Mass = 50000/1000

= 50 kg

Now,

Potential energy = m × g × h

= 50 × 10 × 30

= 15000 joules

Hence, the potential energy of given body is 15000 joules
