Please consider the possibility of equilibrium in the system of the charges of the same polarity. Two charges q= -1C and q2 = -2C are separated by the distance rof 1m. Please find if it is possible to introduce a third charge q3 of -0.2C between two charges q1 and q2 such that this charge will be in the equilibrium? If this is possible, find the distance d. Will the equilibrium be stable? 91 93 1m 92
