In an imaginary atmosphere, the air exerts a small force $F$ on any particle in the direction of particle's motion. A particle of mass $m$ projected upward takes time $t_{1}$ in reaching maximum height and $t_{2}$ in the return journey to the original point, then which of the following is true?

t_{1}=t_{2}

t_{1}>t_{2}

t_{1}<t_{2}

When its going up there are the gravitacional force and the force of the air againdt he moviment and when is going into the floor there is the air for e againd the moviment thus the velocity is greater when going upside down
