Question

Two projectiles $A$ and $B$ are thrown with the same speed but angles are $40^{\circ}$ and $50^{\circ}$ with the horizontal. Then

• A. A will fall earlier
• B. B will fall earlier
• C. both will fall at the same time
• D. None of these

Answer 1

Answer: (A)

$T=\frac{2 u \sin \theta}{g}$, lesser is the value of, lesser is $\sin$ and hence lesser will be the time taken. Hence $A$ will fall earlier.
