Cyclotron is a device which is used to
- a.measure the charge
- b.measure the voltage
- c.accelerating electrons
- d.accelerating protons
Answer: (D) accelerating protons
A cyclotron uses a magnetic field and an alternating electric field between two 'dees' to accelerate heavy positive particles such as protons and deuterons. It is unsuitable for electrons, whose mass rises quickly with speed and throws them out of step, and it does not measure charge or voltage.
