Question

Answer for this and along with units

Answer 1

Solution :-

Given,

• Mass of body = 2kg
• Height = 3m
• g ( acceleration due to gravity ) = 10 m/s²

We need to find ,

• Gravitational potential energy (P.E) = ?

Using ,

• Potential energy = mass × g × height

Substituting known values we have ,

⇒ P.E = 2 × 10 × 3 . kg × m × m/s²

⇒ P.E = 60 kgm²/s²

⇒ Potential energy ( P.E ) = 60 J

Here , J is joules that is S.I. unit of P.E that's equal to kgm²/s²

Hence, potential energy ( P.E ) = 60 J

Answer 2

Answer:

60 J

Explanation:

Given:

• Mass of the body (m) = 2 kg
• Hieght (h) = 3 m

To find:

• Gravitaional potential energy (P.E) = ?

Solution:

We know, Potential energy (P.E) = mass (m) × acc due to gravity (g) × hieght (h)

(put the given values)...

→ P.E = 2 × 10 × 3

→ P.E = 60 J

Hence, the Gravitational potential energy of the body is 60 Joules.

Hope it helped you dear...
