Question

Part A Two long, straight wires, one above the other, are seperated by a distance d = 1.69 cm and are parallel to the r -axis. Let the ty axis be in the plane of the wires in the direction from the lower wire to the upper wire. Each wire carries current 37 A in the direction. Find the magnetic force on a negative point charge 83 C moving with velocity 3.42 105 m/s in the ty- direction, when the charge is Midway between the wires Enter your answers separated by commas F, Fy, Fz Submit My Answers Give Up Part B at a distance d/2 cm above the upper wire Enter your answers separated by commas Fa, Fy, F:- Submit My Answers Give Up Part C At a distance d/3 below the lower wire Enter your answers separated by commas

Explanation / Answer

a] By symmetry magnetic field is zero, so is magnetic force.

Fx,Fy, Fz = 0,0,0 N

b] Force = qvB

= - 83e-6*3.42e5*(2e-7*37*(1/(0.5*0.0169) + 1/(1.5*0.0169)))

= - 0.0331 N

Fx, Fy, Fz = - 0.0331, 0, 0 N

C) again F = - 83e-6*3.42e5*(2e-7*37*(3/0.0169 + 3/(4*0.0169)))

= 0.04661 i N

So Fx, Fy, Fz = 0.04661, 0, 0 N
