(i) The electric field at a point 10 cm away from a charge P as in FIGURE 1 is 2.7 x 10 NC-1. Determine the charge of P.
(ii) a charge Q is placed 10 cm away from charge P. When charge Q is moved horizontally to the right to a position 5 cm from its initial position, there is a 0.54 J change in its electric potential energy of the system. What is the charge of Q?
(iii) Sketch the electric force vectors on charge P and Q.
(iv) If charge Q is again moved horizontally to the right to a new position, and the electric force on it is -4.05 N; how far apart is charge Q from charge P?
(b) Two oppositely charged parallel plates are held 2 mm apart. A 4 x 107 of work is needed to move a 2 C point charge from one plate to the other. Calculate the electric field between the plates.

When applying kirchhoff's rules, one of the essential steps is to mark each resistor with plus and minus signs to label how the electric potential changes from one end of the resistor to the other. the circuit in the drawing contains four resistors, each marked with the associated plus and minus signs. however, one resistor is marked incorrectly. which one is it?
