In uniform circular motion, what is true about the direction of the net force relative to the velocity?
Velocity v=v₀+at. Starting from rest, v=at. With a=(ax i+ay j), magnitude |v|=t√(ax²+ay²) per NCERT vector addition. Substituting ax, ay, t gives |v| equal to It is perpendicular to velocity. Hence option B is correct.
