Statement I: For a projectile launched and landing at the same horizontal level, the maximum range is obtained at a projection angle of $4 5^{\circ}$ . Statement II: For a projectile launched from the top of a cliff and landing at its base, the angle for maximum range is greater than $4 5^{\circ}$ .

Options:

Answer:

Solution:

Statement I is the standard result for level ground. For a launch above the landing level the optimum angle is less than $4 5^{\circ}$ , so Statement II is false. Option C.
