A particle is moving along a straight line parallel to x-axis with constant velocity and position vector is vthati+bhatj . Find angular momentum about the origin in vector form :

Statement-I : If two particles, moving with constant velocities are to meet, the relative velocity must be along the line joining the two particles. Statement-II : Relative velocity means motion of one particle as viewed from the other.

A particle is moving along a straight line with increasing speed. Its angular momentum about a fixed point on this line :

Assertion: When a particle moves with constant velocity its average velocity, its insttantaneous velocity and its speed are all equal in magnitude. Reason: If the average velocity of a particle moving on a straight line is zero in a time interval, then it is possible that the instantaneous velocity is never zero in the internal.

An ant travels along a long rod with a constant velocity ii relative to the rod starting from the origin. The rod is kept initially along the positive x-axis. At t = 0, the rod also starts rotating with an angular velocity w (anticlockwise) in x-y plane about origin. Then

Assertion: In successive time intervals if the average velocities of a particle are equal then the particle must be moving with constant velocity. Reason: When a particle moves with uniform velocity, its displacement always increases with time.
