Two charges are placed at 0 cm and 4 cm, respectively, as shown below. There is one special position x on the positive horizontal axis such that if you place a charge of any sign or magnitude at x, that charge will experience no net electric force. Find x (in centimeters). Hint 1: x is to the right of O B- Hint 2: The expression is equivalent to Vo = = for positive numbers. QA = 2.0C Qg = -0.5 C + 0 1 2 3 4 5 6 7 8 9 10 cm
