Unformatted text preview: adius) is used to keep a proton in a perfectly circular orbit. The solenoid has 1000 windings per meter of length and has a radius of 1 m. If the proton has a velocity magnitude of v = 1.5 ×106 m/s , what is the minimum current needed to keep the proton orbiting within the confines of the solenoid in a plane perpendicular to the solenoid axis? The proton mass is mp = 1.67 ×10−27 kg and its charge is q = +1.6 × 10−19 C . r p (1) 12,500 A (2) 78,000 A (3) 25,000 A (4) 12.5 A (5) 1.6x10- 7 A 4. A series RLC circuit is driven...
