What is the value of potential energy of a body at the height where the value of 'g' is zero?
Correct answer: A. Zero
- A. Zero
- B. Negative
- C. Maximum
- D. mgh
Explanation
Potential Energy = mass x acceleration due to gravity (g) x height g = 0 P.E = m x 0 x h P.E = 0 J

About Work and Energy
Work transfers energy when a force causes displacement, while kinetic energy, gravitational potential energy and power describe motion, position and the rate of energy transfer. The work-energy theorem links net work with change in kinetic energy, and efficiency accounts for energy losses rather than treating them as energy destruction.
