Q14 of 37 Page 21

For a particle performing uniform circular motion, choose the correct statement(s) from the following:


It is given that a particle is performing uniform motion, suggesting that particle’s speed is constant. Also from the figure, we can see that the particle’s velocity vector is always perpendicular to the radius vector. But since, particle’s direction is always changing; therefore, it is accelerating even though speed is constant. Angular momentum’s direction will always be perpendicular to the plane of the circular path.

A particle slides down a frictionless parabolic (y = x2 ) track (A – B – C) starting from rest at point A (Fig. 4.2). Point B is at the vertex of parabola and point C is at a height less than that of point A. After C, the particle moves freely in air as a projectile. If the particle reaches highest point at P, then
