In a cyclotron, the orbital radius of protons with energy 300 kev is 16.0 cm . you are redesigning the cyclotron to be used instead for alpha particles with energy 300 kev . an alpha particle has charge q=+2e and massm=6.64×10−27kg .
if the magnetic field isnt changed, what will be the orbital radius of the alpha particles?

Explanation:

The radius of the circumference described by a particle in a cyclotron is given by:

m is the particle's mass, v is the speed of the particle, q is the particle's charge and B is the magnitude of the magnetic field.

Kinetic energy is defined as:

Solving this for mv:

Replacing (2) in (1):

For protons, we have:

For alpha particles, we have:

Dividing (4) in (3):

adding a(n) to an electric circuit would increase the magnetic field around a wire;

b. solenoid

a solenoid is a type of electromagnet whose purpose is to generate a controlled magnetic field.

if the purpose of the solenoid is instead to impede changes in the electric current, a solenoid can be more specifically classified as an inductor rather than an electromagnet.
