As shown in the figure a body of mass `m` moving horizontally with speed `sqrt(3) m//s` hits a fixed smooth wedge and goes up with a velocity `1v_(t)` in the vertical direction. If `/_` of wedge is `30^(@)`, the velocity `v_(f)` will be `:` A. `sqrt(3)m//s`B. `3m//s`C. `(1)/(sqrt(3))m//s`D. this is not possible |

Answer» Correct Answer - D Velocity along the plane does not change So `sqrt(3)Sin f o^(@)=V_(1)sin 30^(@)` `rArrV_(1)=3m//sgt sqrt(3)m//s` Which in impossible `:. Ans. (D)` |
