The reation between the time t and position x for a particle moving on x-axis is given by `t=px^(2)+qx`, where p and q are constants. The relation between velocity v and acceleration a is asA. `a prop v^(3)`B. `a prop v^(2)`C. `a prop v^(4)`D. `a prop v` |

Answer» Correct Answer - A `(dt)/(dx) = 2px + q` `rarr v = (dx)/(dt) = (1)/(2px + q)` `a = (-2p)/((2px + q)^(3)) rarr a prop ((1)/(2px + q))^(3)` `rArr a prop v^(3)` |
