As shown in the figure, an electron is fired with a speed of 3.84 x 106 m/s through a hole in one of the two parallel plates and into the region between the plates separated by a distance of 0.26 m. There is a magnetic field in the region between the plates and, as shown, it is directed into the plane of the page (perpendicular to the velocity of the electron). Determine the magnitude of the magnetic field so that the electron just misses colliding with the opposite plate.

Provide your answer in volts, use scientific notation. Use three significant figures in your response. Ignore D2L's comment about "highest possible power", present your answer in format X.YZ*10^N. Note: Your answer is assumed to be reduced to the highest power possible. Your Answer: |x10 Answer units B) Two point charges, q1 =4.0 nC and q2 =-5.0 nC are located at A =(0.5,-1.0)m and B =(-2.6,-3.6)m, respectively. Calculate the electric potential due to these point charges at P =(-5.2,-2.7)m. Express your answer in volts, use appropriate symbols. Express your answer rounded to have at least one digit after the decimal, do not use scientific notation. Using more significant figures will not be considered incorrect, using fewer may result in errors due to rounding. Your Answer: Answer units
