The work done in moving a body of mass 2 ~kg to a height of 4 ~m from the surface of the earth is (Acceleration due to gravity =10 ~ms ⁻² )
Options
- A10 ~J
- B20 ~J
- C40 ~J
- D80 ~J
Correct answer
D. 80 ~J
Step-by-step solution
Mass of body, M=2 kg Height, H =4 ~m work done to lift a body = potential energy of body aligned & W=m g h=2 10 4 & W=80 ~J aligned
