2. Three point charges q, 2q, and -3q where q = 2 x 10-3 C are located at the corners of an equilateral triangle with side length L = 0.5 m as shown below: L 2q0 3q L a) What is the total electrostatic force on the charge q at the top of the triangle? b) What is the electric field at the center of the triangle? 3. Three point charges q1, 92, and q3 are located at the corners of a rectangle with side lengths 0.6 m and 0.8 m: 0.6 m 0.8 m We know that q1 = 2 x 10-8 C but 92 and 93 are unknown. If the total electric field at the empty corner is zero, what are 92 and 93
