1)we know that v=rw(w=angular velocity)...if i keep w a constant and keep on increasing r ,at some value of r (though it is practically impssible to have an object with such a large r)we have the velocity of the object greater than velocity of light....how to resolve this???? 2)we have pi=circumference/diameter...but when a body revolves with a vwey large velocity (consider an electron in a cyclotron)according to lorentz's transformation we get a variation in the measured value of circumference and hence in the calculated value of pi....how do we resolve this?????
