What is the deflection if mandrel (Taper shank) of working length 75 mm?

What is the deflection if mandrel (Taper shank) of working length 75 mm? Correct Answer Less than 0.65 μm

The free end deflection of mandrels should be less than 0.65 μm for those having a working length of 75 mm and for those having a working length of 505 mm, it is less than 5.8μm.

A displacement sensor (a dial indicator) measures the lateral displacement of a mandrel mounted on the taper hole inside a drill spindle. The mandrel axis is an extension of the drill spindle taper hole axis and the protruding portion of the mandrel surface is perfectly cylindrical measurements are taken with the sensor placed at two positions P and Q as shown in the figure. The readings are recorded as Rx = maximum deflection minus minimum deflection, corresponding to sensor position at X, over one rotation. If RP = RQ > 0, which one of the following would be consistent with the observation?
