A body of mass 10 kg is raised to a height of 2 m. If the acceleration due to gravity is 9.8 m/s^2, what is the work done?
Q1. A body of mass 10 kg is raised to a height of 2 m. If the acceleration due to gravity is 9.8 m/s^2, what is the work done?
Answer: 196 J
Explanation: Work done = mgh = 10 kg * 9.8 m/s^2 * 2 m = 196 J. Option B is incorrect due to rounding g to 10 m/s^2.
