Question 5 of 6 Map deb istione witten by Sean Coedry at Waheys Stete Communit College Sapling Learning A tiny dust particle (m 2.70 x10 kg) has a charge of 2. 15 10 C when field points out of your screen. it enters an MRI machine with a speed of 7.12 m's. The machine's strong magnetic field (B = 2.53 T) and the particle are shown in the diagram. The Answer the three questions below, using three significant figures. Part A Which path will the particle take while inside the field? O A (straight through) O B (curl to the left) O C (curl to the right) O D (curl out of the screen-not pictured) O E (curl into the screen - not picture) Part B: What is the magnitude of the force (F) acting on particle? Number Part C What widd he the rardius of cunvature of the narticle as it travels throcsh b mooentin Ralen ?O Previous 0 Next I Save And Exit

Explanation / Answer

1) Since magnteic field in out of page and being a positice charge

a positive charge deflects to the left

option B it is

2)

magnetic force F = qv B

F = (2.15 e -4 * 7.12 * 2.53)

F = 3.87 *10^-3 N

3)

radius r = mv/qB

r = (2.7 e -5 * 7.12)/(2.15 e -4 * 2.53)

r = 35.34cm
