3. Question 6 {1 point] Retake question In the figure the charges are C91=0a92403f33=0 {Pd/Q1203 (32303 (33:0 A Question 7 (1 point) Retake question In the picture shown, a proton moves with speed (1.7690x10^6) m/s in a magnetic field with strength (3.47x10^2) T. 120 0 B What is the magnetic force (in N) on the proton? Use positive for out of the page and negative for into the page. Note: Your answer is assumed to be reduced to the highest power possible. Your Answer: x10 AnswerA Question 8 (1 point) Retake question An electron moving perpendicular to a magnetic field of 3.96 x10-3 T follows a circular path of radius 2.44 mm. What is the electron's speed? Your Answer: Answer A Question 9 (1 point) Retake question A particle orbits in a magnetic field with a radius of 1 m. If the mass of the particle is doubled, while everything else remains the same, what is the new radius of the orbit? 0.5 m 1m 2 m 4m A Question 10 (1 point) Retake question A proton moves in a circular path perpendicular to a uniform magnetic field of (4.260x10^0) T. The radius of this path is (6.1200x10^-3) m. Calculate the energy of the proton in joules. Note: Your answer is assumed to be reduced to the highest power possible
