A/an 8-milligram, 3-millicoulomb charge is fired to a uniform magnetic field via a 290-volt potential difference which acts as an accelerator to the charge. If
the initial velocity of the object is 46 kilometers per second, determine the magnitude of the magnetic field (measured in tesla) so that the radius of curvature
of the object is 4 meters. Express your answers accurate to four decimal places, whenever applicable.
The magnetic field in a cyclotron is 0.77 T. What must the minimum radius of the dees be in metres, if a proton beam is to be produced with a maximum speed of 4.8×107 m/s? Give answer to 2 decimals.
