Problem 1 (20 points) The charges q1 92, and q3 are arranged at the corners of a rectangle shown below. Find the direction and magnitude of the net electrostatic force exerted on the point charge q3 in the figure below. Let h = 8.02 cm, d = 18.2 cm, q1 - +3.41 pC, q2 = +1.35 HC, and q3 - -4.23 HC. Problem 2 (20 points) The figure below shows a system consisting of three point charges, q1 = +1.72 HC, q2 = +4.37 HC, and q3 = +1.72 HC at the vertices of a right triangle of base b = 1.12 cm and height h = 1.98 cm. Find the magnitude and direction of the electric field at point P, which is halfway between charges q, and q3. Hint: First find the angle, 0, made between the base, b, and the line extending from q2 to point P. Problem 3 (20 points) A charge of q1 =+8.49 HC is at the origin x = 0. A charge q2 = -2.25 JC is at x = 20.0 cm. (a) (5) Find the electric potential at x = 10.0 cm. (b) (8) Find the point between x = 0 and x = 20.0 cm where the electric potential vanishes. (c) (7) Find the location in the region x > 20.0 cm where the electric potential vanishes. XCO X= 10,Orm * # 20.0 cm
