Question

# In the figure shown, a person wants to raise a block lying on the ground to a height h. In both the cases if time required is same then in which case he has to exert more force. Assume pulleys and strings light.

- (i)
- (ii)
- same in both
- Cannot be determined

## The correct answer is: (i)

### Since, at_{2} Þ a should be same in both cases, because h and t are same in both cases as given.
