Answer» In List - I condition on initial velocity $\to u$ , force $\to F$ and acceleration $\to a$ of a particle is given. Resultant motion is described in List-II. Match List-I with List-II $\begin{matrix} List-I & List-II (I) & \to u \times \to F = 0 and & (P) & Path will be \to F = constant & circular path (II) & \to u . \to F = 0 and & (Q) & Speed will increase \to F = constant (III) & \to v . \to F = 0 all the time & (R) & Path will be and \| \to F \| = constant & straight line and the particle always remains in one plane (\to v is instantaneous velocity) (IV) & \to u = 2^i - 3^j and & (S) & Path will be acceleration at all time & parabolic \to a = 6^i - 9^j \end{matrix}$
