उत्तर
A Class II lever will always have M.A. > 1.
Explanation:
In a Class II lever, the load is located between the fulcrum and the effort. This arrangement means the effort arm is always longer than the load arm. Since the Mechanical Advantage (M.A.) is calculated as the ratio of the effort arm to the load arm, the M.A. is always greater than 1, meaning it acts as a force multiplier.
