A point charge q2 = -3.9 uC is fixed at the origin of a co-ordinate system as shown. Another point charge 91 = 3 °C is is initially located at point P, a distance di = 8.7 cm from the origin along the x-axis qi Р 1) What is APE, the change in potenial energy of charge 91 when it is moved from point P to point R, located a distance d2 = 3.5 cm from the origin along the x-axis as shown? J 2) 93 ch R (91) x 94 The charge q2 is now replaced by two charges q3 and 24 which each have a magnitude of -1.95 uC, half of that of q2. The charges are located a distance a = 2.1 cm from the origin along the y-axis as shown. What is APE, the change in potential energy now if charge q1 is moved from point P to point R? J 3) 93 R (91) di x P 94 What is the potential energy of the system composed of the three charges 91, 93, and 94, when q, is at point R? Define the potential energy to be zero at infinity.
4) fy (93) ch a R 91 di а p 95 The charge 94 is now replaced by charge qs which has the same magnitude, but opposite sign from 94 (i.e., q. = 1.95 uC). What is the new value for the potential energy of the system? = J 5) dz R dy 42 91 (96) X di Р Charges qz and q5 are now replaced by two charges, 42 and 46, having equal magnitude and sign (-3.9uC). Charge q2 is located at the origin and charge 46 is located a distance d=dj + d2 = 12.2cm from the origin as shown. What is APE, the change in potential energy now if charge q1 is moved from point P to point R? = =
