1. An electric circuit was accidentally constructed using a capacitor instead of the required value. Without removing the capacitor, what can a technician add to correct this circuit? Draw a scaled diagram to illustrate the image formation in this case

2. Two charges form the base of an equilateral triangle, with the apex being point P right above the midpoint of the line joining the two charges Calculate: a) the electric field (both magnitude and direction) at P. b) the electric potential at point P. c) the electric force (both magnitude and direction) on a third identical charge placed at P. d) the work done to bring the third identical charge from very far away to point P.
