Question

if the mass of a body is 20g and it is raised to height 10m above the ground calculate it's potential energy​

Answer 1

Given:

Mass = 20g = $\Large \frac{20}{1000}$ = 0.02kg

Height = 10m

Find: Potential energy = ?

Explanation:

Potential energy = mass × acceleration due gravity × height

So, potential energy = 0.02×10×10 = $\bf{2J}$

OR

Potential energy = 0.02 × 9.8 × 10 = $\bf{1.96 J}$

Answer 2

Answer:

0.2 J

Explanation:

PE = mgh

PE = 20 × $10^{-3}$ × 10

PE = 0.2 J
