work done = change in kinetic energy
therefore, no work has been done because kinetic energy is constant and work will only be done when kinetic energy changes .
therefore if work is 0J then,
W=Fs
0=F*1
0/1=F
0=F
therefore 0N force is acting on the body.
i hope that this will help u......................^_^
Kinetic energy is 25 J by the way not 0
and its 1 m RADIUS..So, first u have to calculate the circumference...
On which it is moving
wt do u mean by constant kinetic energy
Mass of the body ?

The body has constant kinetic energy. So it is moving with a constant speed or it is in uniform circular motion.

Let the mass of body = m
velocity = v
