In the time taken by the projectile to reach from `A` to `B` is `t`. Then the distance `AB` is equal to. .A. `(ut)/(sqrt3)`B. `(sqrt(3) ut)/2`C. `sqrt3 ut`D. `2ut` |

Answer» Correct Answer - a Horizontal component of velocity, `u_(H)=ucos 60^(@)=u/2` `AC=u_(H)xxt=(ut)/2` And `AB=AC sec 30^(@)` n `=((ut)/2)(2/(sqrt(3)))=(ut)/(sqrt(3))` |
