If the instantaneous velocity of a particle projected as shown in figure is given by $v =a \hat{ i }+(b-c t) \hat{ j }$, where $a, b$, and $c$ are positive constants, the range on the horizontal plane will be

A

$2 a b / c$

B

$a b / c$

C

$a c / b$

D

$a / 2 b c$

Solution

(a)

$u_x=a, u_y=b, g=c$

$R=\frac{2 u_x u_y}{g}=\frac{2 a b}{c}$
