Q: A ball weighing 0.1 kilogram is dropped from a stationary position when it falls from a distance of 2 meters, then what will be the work done by the force of gravity
  • A. 1.96 J
  • B. - 1.96 J
  • C. - 0.98 J
  • D. 0.98 J
Correct Answer: Option A - Given, Mass of ball (m) = 0.1 kg Total height (h) = 2m Acceleration due to gravity (g) = 9.8 m/s² Here, work done by the gravitational force = potential energy of ball at 2 m height. W = 0.1×9.8×2=1.96 J
A. Given, Mass of ball (m) = 0.1 kg Total height (h) = 2m Acceleration due to gravity (g) = 9.8 m/s² Here, work done by the gravitational force = potential energy of ball at 2 m height. W = 0.1×9.8×2=1.96 J

Explanations:

Given, Mass of ball (m) = 0.1 kg Total height (h) = 2m Acceleration due to gravity (g) = 9.8 m/s² Here, work done by the gravitational force = potential energy of ball at 2 m height. W = 0.1×9.8×2=1.96 J
