A) \[+\,490\,J\]
B) \[-\,490\,J\]
C) \[-\,980\,J\]
D) \[+\,980\,J\]
Correct Answer: A
Solution :
Since, the body is moving in the direction of force, therefore work done by gravitational force will be positive. Work done, W = F. s = mgh \[=10\times 9.8\times 5=480\,J\]You need to login to perform this action.
