Q. A proton is accelerated from rest through a potential difference of 2.5 kV and then moves perpendicularly through a uniform 0.60 T magnetic field. What is the radius of the resulting path?
Q. A car of mass = 1200 traveling at 65.0 enters a banked turn covered with ice. The road is banked at an angle , and there is no friction between the road and the car's tires. What is the radius of the turn if = 20.0 (assuming the car continues in uniform circular motion around the turn)?
