APP2 Unit 5 Test Review




1. Three parallel wires lie in the corners of a square, side length of 1cm. Each has a
current of 5 A. Wires A and B are directed out of the page, while C is directed
into the page.
a. Determine the magnitude and direction of the net magnetic field at the top
right corner of the square.
b. Determine magnitude and direction of the force on a proton if moving out
of the page at
1.5 E5m/s at the corner.
c. If the direction of the currents of A and B were reversed, determine the
resulting magnetic field at the corner.




2. An electron is placed in Region I, as shown. It is accelerated through the
potential difference and enters Region II with a velocity of 7 E6 m/s where it
strikes the photoelectric detector a distance of 0.35 m above the entry point.
a. Calculate the potential difference set up across Region I.
b. Determine the magnitude and direction of the magnetic field in Region II.
