A point charge 42 = -0.4 C is fixed at the origin of a co-ordinate system as shown. Another point charge 44 = 2.9 C is is initially located at point P, a distance d. = 8.6 cm from the origin along the x-axis dh R (92) (91 Р 1) What is APE, the change in potenial energy of charge 4, when it is moved from point P to point R, located a distance dz = 3.4 cm from the origin along the x-axis as shown? -0.185 Submit
2) (93 de R X (91) Р 94 The charge 42 is now replaced by two charges 43 and 4 which each have a magnitude of -0.2 PC, half of that of 42. The charges are located a distance a = 2 cm from the origin along the y-axis as shown. What is APE, the change in potential energy now if charge 4is moved from point P to point R? Submit 3) (93) d2 R (91) 94 Р What is the potential energy of the system composed of the three charges 91, 93, and 44, when 4 is at point R? Define the potential energy to be zero at infinity. Submit 4) 43 d2 R (91 95 The charge 44 is now replaced by charge 4 which has the same magnitude, but opposite sign from 04 (i.e., 45 = 0.2 pC). What is the new value for the potential energy of the system? J Submit
