Two projectiles are thrown simultaneously in the same plane from the same point. If their velocities are `v_(1)` and `v_(2)` at angle `theta_(1)` and `theta_(2)` respectively from the horizontal, then answer the following question If `v_(1) = v_(2)` and `theta_(1) gt theta_(2)`, then choose the incorrect statementA. Particle 2 moves under the particle 1B. The slope of the trajectory of particle 2 with respect to 1 is always positiveC. Both the particle will have the same range if `theta_(1) gt 45^(@)` and `theta_(2) lt 45^(@)` and `theta_(1) + theta_(2) = 90^(@)`D. none of these |

Answer» Correct Answer - A `x=v costheta t = 50 xx(3)/(5) xx2=60m` `y=usinthetat-(1)/(2)g t^(2)= 50xx(4)/(5)xx2-(1)/(2)xx10xx2^(2)=60m` `d=sqrt(x^(2)+y^(2))` `=sqrt(60^(2)+60^(2))=60sqrt(2)m` |
