A CNC worktable is driven in a linear direction by
a lead screw connected directly to a stepper motor.
The pitch of the lead screw is 5 mm. The stepper
motor completes one full revolution upon receiving
600 pulses. If the worktable speed is 5 m/minute
and there is no missed pulse, then the pulse rate
being received by the stepper motor is
(a) 20 kHz
(b) 10 kHz
(c) 3 kHz
(d) 15 kHz
