A projectile attains its maximum height when the angle of projection is?
A
30°
B
45°
C
60°
D
75°
E
90°
Verified Correct Answer: E.
Physical Principles & Numerical Solution
At an angle of 90^\circ, the projectile is launched straight up, maximizing its height. While other angles can also achieve significant heights, 90^\circ results in the highest possible elevation.
