What is the cyclotron frequency of a particle of mass m = 3.0x 10'25 kg with a charge 78 that is moving in the magnetic eld of 41.2 MT. Express your answer in hertz, with a precision of two places after the decimal. A circular loop of radius r = 0.069 m carries a counter-clockwise current lL = 0.42 A. What is the current in the innite wire located distance d = 0.220 m if the net magnetic eld in the center of the loop is equal to zero? 3' d = 0.220 m Enter your answer in amperes with the precision of two places after the decimal. Indicate with a sign whether the conventional current is to the left (negative) or to the right (positive)
