A particle thrown up vertically reaches its highest point in time \( t_{1} \) and returns to the ground in further time \( t_{2} \). The air resistance exerts a constant force on the particle opposite to its direction of motion
(A) \( t_{1}t_{2} \)
(B) \( t_{1}=t_{2} \)
(C) \( t_{1}t_{2} \)
(D) may be \( (\mathrm{A}) \) or \( (\mathrm{C}) \) depending on the ratio of the force of air resistance to the weight of the particle.
