Answer
This statement is false. A cyclotron primarily accelerates charged particles such as protons and ions, not neutrons, which are neutral.
Step 2
B A cyclotron uses a magnetic field to increase the speed of particles.

Answer
This statement is partially true but misleading. While a magnetic field is used to keep particles in a circular path, it's the electric field that accelerates the particles.
Step 3
C A cyclotron uses an alternating potential difference at a constant frequency.

Answer
This statement is true. A cyclotron operates by using an alternating electric field to accelerate charged particles at a fixed frequency, which enhances their speed.
Step 4
D A cyclotron uses an electric field to keep particles moving in a circular path.
