A particle is projected in `x-y` plane with `y-`axis along vertical, the point of projection being origin. The equation of projectile is `y = sqrt(3) x - (gx^(2))/(2)`. The angle of projectile is ……………..and initial velocity is ………………… .A. `1ms^(-1)`B. `2ms^(-1)`C. `3ms^(-1)`D. `1.2 ms^(-1)` |

Answer» Correct Answer - B Comparing with `y = x tan theta - (gx^(2))/(2u^(2)cos^(2)theta)` we have, `tan theta = sqrt(3)` or `theta = 60^(@)` and `u^(2) cos^(2)theta = 1` or `u = sec theta = sec 60^(@) = 2 ms^(-1)` |
