Imagine 3 charges, separated in an equilateral triangle as shown above, with L = 2.0 cm, q = 1.0 nC. What is the magnitude and direction of the force felt by the upper charge? -2q L +9 +9 Your answer What is the magnitude of the force that a 25-JC charge exerts on a -10-UC charge 8.5 cm away? Your answer Two point charges, QA = +8 UC and QB = -5 UC, are separated by a distance r = 10 cm. What is the magnitude of the electric force? Your
