Technical Sciences QUESTION 3 (Start on a new page.) 3.1 Two charges, X and Y, with charges of + 4 nC and -2 nC respectively, are placed 8 cm apart. A point charge, P, is placed 2 cm from Y, as shown in the sketch below. X 8 cm Y SEPTEMBER/2021 2 cm - 2 nC P + 4 nC 3.1.1 Define the term electric field at a point. (2) 3.1.2 Briefly explain how you will be able to determine the direction of the electric field around a charged object. (3) 3.1.3 Draw the electric field pattern between two oppositely charged particles. (3) 3.1.4 Calculate the net electric field strength at point P due to X and Y. (7) [15]
