Three particles are projected in air with the minimum possible speeds, such that the first goes from Ato B, the second goes from 5 to C and the third goes from C to A. Points A and Care at the same vertical level. The two inclines make the same angle a with the horizontal as shown. Thenthe relation among the projection speeds of the three particles is :A. `u_(3)=u_(1)+u_(2)`B. `u_(3)^(2)=2u_(1)u_(2)`C. `1/u_(3)=1/u_(1)+1/u_(2)`D. `u_(3)^(2)=u_(1)^(2)+u_(2)^(2)` |
