Two projectiles {A} and {B} are thrown from the same point with velocities v and (0.5) v respectively. If {B} was thrown at an angle 45^{\circ} with the horizontal, find the angle with which {A} was projected, if it is known that both {A} and {B} have equal ranges?

Correct Answer is : 12Sin−1(14)

\frac{1}{2} Sin^{-1}(\frac{1}{4})

\frac{1}{2} Sin^{-1}(\frac{1}{8})
