Work done by centrifugal force is alwys zero.
Centifugal force occurs in circular motion.
while the central force acts along the radius, the motion of the body at that instan is tangential.
SInce the angle between radius and tangent is 90 degree. work done is zero as it is the dot product of force and displacement
 
W= FScostheta
As cos 90 = 0
work done is zero.
