Name
A charged particle (|q| = 945 μC) enters a uniform magnetic field and follows a circular path, with a radius of 0.780 km, as shown below. The magnetic field has a value of 488 mT and the speed of the particle is 155 km/s.
a. Is the particle positively or negatively charged?
b. What is the mass of the particle?
c. Determine the cyclotron frequency.
d. How long does it take for the particle to make one complete circle?
Please tell me how to solve this.
