Question 3 [ 9 points]: A proton moves through a magnetic field at
20.7%
of the speed of light. At one location, the field has a magnitude of 0.00623 T and the proton's velocity makes an angle of 109 degrees with the field. Use
C=2.998\times 10^(8)(m)/(s)
for the speed of light and
e=1.602\times 10^(-19)C
as the elementary charge. What is the magnitude
F_(B)
of the magnetic force acting on the proton at that location?
