2. Three point charges are q, = +6.8 mC, q2 = +55 µC and q; = -78 µC are placed in a line respectively. The charge at the center (2) is 45 cm away from the charges at the both ends. a. What is the magnitude of electrostatic force on q, exerted by q,? b. What is the magnitude of electrostatic force on q, exerted by q,? c. What is the net electrostatic force on q, due to the other two charges?
