A proton (charge +1.60×10−19C) and an electron (charge
-1.60×10−19C) are both moving in the xy-plane with the same speed,
5.20×105m/s. The proton is moving in the +y-direction along the
line x = 0, and the electron is moving in the -y-direction along
the line x = +3.00 mm. At the instant when the proton and electron
are at their closest approach, what is the magnitude of the
magnetic force that the proton exerts on the electron?

Three charges are fixed to an xy coordinate system. A
charge of +19C is on the y axis at y = +3.7 m. A
charge of -9.8C is at the origin. Lastly, a charge of +46C is on
the x axis at x = +3.7 m. Determine
(a) the magnitude and (b)
direction of the net electrostatic force on the charge at
x = +3.7 m. Specify the direction as a positive angle
relative to the +x axis.

In (Figure 1), a beam of protons moves through a uniform
magnetic field with magnitude 2.0 T , directed along the positive
z axis. The protons have a velocity of magnitude
3.0×105 m/s in the x-z plane at an
angle of 30 ∘ to the positive z axis. Find the force on a

Consider two infinite plates, both parallel to the xy plane of a
coordinate system. The top plate is at the height z = +5cm and
carries a uniform charge distribution of ?= +3nC/m2. The bottom
plate is at height z = - 5cm and carries a uniform charge
distribution of ?= -3nC/m2. The space between the plates is filled
with air. Between the plates runs a long wire along the y-axis (at
z=0 and x=0), carrying a current of 10A....

A group of particles is traveling in a magnetic field of unknown
magnitude and direction. You observe that a proton moving at 1.20
km/s in the +x-direction experiences a force of
