Singly charged positive ions are kept on a circular orbit in a cyclotron. the magnetic field inside the cyclotron is 1.981 t. the mass of the ions is 3.67×10-26 kg, and speed of the ions is 2.75 percent of the speed of the light. what is the diameter of the orbit? (the speed of the light is 3.00×108 m/ m)

Therefore the diameter of the orbit is 1.91m

Explanation:

The path followed by the particle is a circle that keeps the relation given by

Re-arrange the equation for r,

From V is equal to speed of ions and there is a procent for this 'real speed' we have

Replacing in the previous equation,

Therefore the diameter of the orbit is 1.91m

c) up is the direction the magnetic force is acting on the charge.
