Question

Find the gravitational potential of energy of an object whose mass is 20kg and kept on a table top of height 50 m from ground. (take g = 10 N kg).​

Answer 1

Explanation:

Given,

Mass of object m=10kg.

Height h=6m.

Acceleration due to gravity g=9.8m/s

2

Potential Energy of object P.E=m×g×h

⇒mgh=10×9.8×6=98×6

=588J

Energy possessed by the object is 588Joule.

Answer 2

Explanation:

Given,

• Mass of object m = 20 kg .

• Height h = 50m .

• Acceleration due to gravity g = 10N

Potential Energy of object 5.E=m×g×h

$\Rightarrow \: mgh=20 \times 10 \times 50=10000$

• =10,000J

Energy possessed by the object is 10,000Joule.
