200 J
Attempted by 75 students.
Show answer & explanation
Correct answer: B
The energy possessed by a body placed at a height is called Gravitational Potential Energy (PE).
Formula:
Given:
Mass (m) = 2 kg
Gravity (g) = 10 m/s²
Height (h) = 5 m
Calculation:
PE=2×10×5
PE=100J
Therefore, the energy possessed by the body is 100 J.
