1. Five(5) charges are located as shown with a = 8.00 cm, b = 6.00 cm, and each charge is 10.0 cm from the origin. The charges areq1 =q2 = q3 = -50.0 nC, q4 = q5 = +50.0 nC.
a. Determine the magnitude and direction of the electric fieldat the origin.
b. Determine the potential at the origin. Assume V = 0 at infinity (∞).
2. Two long parallel wires each carry a current of i = 12.5 A in opposite directions as shown. The wires are 40.0 cm apart. Determine the total magnetic field, in magnitude and direction form, at point P.
3. A concave mirror with a 40 cm focal length is placed 24 cm in front of an object.
a. Calculate where the image is located and what type of image is it?
b. What is the magnification, relative size and orientation of the image?
c. Construct a ray diagram for this arrangement to locate the image (Use the attached graph paper to draw three rays from the object to determine the location of the image.
