015 (part 1 of 2) 10.0 points Consider a variation of Bohr's 1913 model of the hydrogen atom, where the electron is in a circular orbit of radius 7 x 10 m, and its speed is 1.9021 x 10" m/s. What is the magnitude of the magnetic moment due to the electron's motion? Answer in units of Am-. 016 (part 2 of 2) 10.0 points If the electron orbits counterclockwise in a horizontal circle as viewed from above up- ward. what is the direction of this magnetic moment vector? 1. radially outward 2. radially directed; sometimes inward and sometimes outward 3. upward 4. radially inward 5. downward 017 (part 1 of 2) 10.0 points A circular coil of 528 turns and area 0.73 m- is in a uniform magnetic field of 0.36 T. The maximum torque exerted on the coll by the field is 0.0062 N - m. Calculate the current in the coil. Answer in units of A. 018 (part 2 of 2) 10.0 points Assume the 528 turns of wire are used to form a single-turn coil with the same shape but much larger area. What is the current if the maximum torque exerted on the coll by the field is 0.0062 N . m? Answer in units of A. 019 10.0 points What is the radius of the largest possible cir- cular orbit that a proton with energy 3.7 MeV can have in a 2 T magnetic field? The mass of a proton is 1.67 x 10 2 kg and its charge is 1.609 x 10-P C. Answer in units of m
