Solution
The correct option is B 2nd
- Levers can be used to apply a strong force over a short distance on one end while only applying a modest force (effort) over a longer distance on the other.
- In a wheelbarrow, the fulcrum is at one end and the force applied is on the other end. The weight is situated in the middle of these two.
- In second-class levers, the load is between the effort (force) and the fulcrum.
- Thus, A wheelbarrow is an example of a second-class lever.
Hence, option (B) is correct.
