Two projectiles A and B are projected with same
\( \mathrm{P} \)
speed at an angle \( 30^{\circ} \) and \( 60^{\circ} \) to the horizontal, then
W
which of the following is not valid. Where \( T \) is total time of flight, \( H \) is maximum height and \( R \) is horizontal range.
(1) \( H_{A}=3 H_{B} \)
(2) \( T_{B}=\sqrt{3} T_{A} \)
(3) \( R_{A}=R_{B} \)
(4) \( H_{B}=\sqrt{3} H_{A} \)
