[6]31 A point charge, Q3 = +458 JC, is placed at a point in an electric field where the electric potential is 555 kV. Determine the potential energy that the charge will have at that location. (Assume that the potential energy is zero at infinity ) Give your answer in the form "+/-a.bc J". [4132 The amplitude of an AC voltage is 25,000 volts. What is its RMS value? Give your answer in the form "ab.c" kV [8]33. The magnetic field through the rectangular loop shown in the 25.6 cm figure changes according to the relation B(t) = (1200 - 31.0t ) T with t in seconds. The resistance of the loop is 6.22 ml2 . B Based on the above information give the statement(s) that is (are) TRUE
