A boy standing at the point O in the given diagram throws a ball three times with the same force, but projecting it along different inclinations from the ground. The results of the throws have been plotted in the diagram.Which one of the following is a valid conclusion? Height O Distance

aThe larger the initial inclination, the longer the throw
b​The larger the height reached, the longer the throw
c​The larger the height reached, the shorter the throw
d​The larger the initial inclination, the greater the height reached UPSC GS Paper-I PYQs 588
✓ Correct answer: d) ​The larger the initial inclination, the greater the height reached UPSC GS Paper-I PYQs 588
ExplanationThe height of a projectile is determined by the vertical component of the initial velocity, which increases with the angle of projection (vsinθ).In the diagram, as the initial inclination increases, the ball reaches a greater height, which aligns with the laws of projectile motion.Therefore, the larger the initial inclination, the greater the height reached is a valid conclusion.239
