A point charge q2 = -3.9 μC is fixed at the origin ofa co-ordinate system as shown. Another point charge q1 =4.5 μC is is initially located at point P, a distance d1= 8.2 cm from the origin along the x-axis
Point R located at d2 = 3.3 cm
The charge q2 is now replaced by two chargesq3 and q4 which each have a magnitude of-1.95 μC, half of that of q2. The charges are located adistance a = 2 cm from the origin
What is the potential energy of the system composed ofthe three charges q1, q3, and q4,when q1 is at point R? Define the potential energy to bezero at infinity.
