A man carries a 5 kg load on his head and moves 10 m along a horizontal path. The work done by him against gravity is:
A50 J
B500 J
CZero
D25 J
✓ Correct Answer: C — Zero
Since the displacement is horizontal and gravity acts vertically, the angle is 90 degrees; hence, no work is done against gravity.
