Solution

The correct option is A Constant in magnitude as well as direction
as the sign of velocity change direction is varying and omega=v/r and that also varies in co ordinate magnitude is also varying

A person applies constant force $\vec{F}$ on a particle of mass m and finds that the particle moves in a circle of radius r with a uniform speed v as seen from an inertial frame of reference.

(a) This is not possible.
(b) There are other forces on the particle.
(c) The resultant of the other forces is $\frac{m v^{2}}{r}$ towards the centre.
(d) The resultant of the other forces varies in magnitude as well as in direction
