  • A
    M.A. = V.R.
  • B
    M.A. > V.R.
  • ✓
    M.A. > 1
  • D
    M.A. < 1
✓

Answer

Correct option: C.
M.A. > 1
M.A > 1
Hint: In class II levers, the load is in between the effort and fulcrum. Thus, the effort arm is always longer than the load arm and less effort is needed to overcome a large load. Hence, M.A > 1
