Two IDENTICAL point charges, X and Y, are placed 2 mm apart. Point P is 3 mm to the right of charge Y. The net electric field at point P is 5,44 × 106 N∙C-1 to the left.
8.1 Define the term electric field at a point. (2)
8.2 Are the charges NEGATIVE or POSITIVE? (1)
8.3 Draw the resultant electric field pattern for charges X and Y. (3)
8.4 Calculate the magnitude of the charge X. (5)
8.5 Charge Y is now replaced by an identical oppositely charged point charge.
How will the magnitude of the net electric field at point P be affected? Choose from INCREASE, DECREASE or REMAIN THE SAME.
Give a reason for the answer. (2)
