What is the magnitude of torque for a body circulating with constant a

1.	What is the magnitude of torque for a body circulating with constant angular speed? Why?
Answer» Solution :Zero. Because `a_(T)=0 THEREFORE veca=a_(r)` and DIRECTION of `a_(r)` towards the CENTRE and hence `\|vectau\|=rFsintheta, theta=180^(@) therefore \|vectau\|=0`
