2. a) Two equal positive charges are on a line established an electric field at a point in the same line of magnitude E = (last two digits of your ID) N/C. If charges are separated by a distance 20cm and the point is 5cm from the first charge, find the value of the positive charge. (k=9x10° Nm³/C³) b) Suppose you have a 5 V battery, a 6 uF capacitor, and a 7 uF capacitor which is acting in an electric field of 8 N/C. (i) Find the equivalent charge and (ii) energy stored, if the capacitors are connected to the battery in series. (€, = 8.854 x 10-12F/m) c) A square of side 50cm is shown in fig. below. Charge arrangements at four corners are A= B = (last two digits of your ID) C, C= D= - (last two digits of your ID) C. What is the electric potential at E due to charge at A, B, C and D? B E. D
