With explanation please Lab Day/Time: Wednesday Homework 9 Magnetic Force Multiple-Choice Problems 9.1 A3nc charge is moving at 50x of the speed of light, in a uniform 03T Wednesday Homework Problem The velocity of the charge is perpendicular to the field. What is the magnitude magnetic field (e m 3x of the Lorentz force on the charge? Ignore any effect of relativity. Select One of the Following a) 0.135N (b) 13.5N (c) 7.5N (d) 00015N Toby Wednesday Homework Problem 9.2 A proton has velocity Magnetic Field Out of Page in the direction drawn when it passes through point P The magnetic field has strength 2T. The proton may follow either trajectory A or trajectory B A proton has charge +1.6x 10 and mass 16 o kg Select the trajectory and calculate the radius of the orbit. Select One of the Following (a) Trajectory A. radius o uszn ajectory A. radius 10.12ra Trajectory B, radius 0.157m (d) Trajectory B, radius 10.12m

Explanation / Answer

9.1

speed

V=0.5c=0.5*3*108=1.5*108 m/s

lorentz force on the charge

F=qvBsin90=qvB

F=(3*10-9)*0.3*(1.5*108)

F=0.135 N
