Exercise 1 30mm w 20mm 1. Calculate the electric field strength at a distance of 6mm from a point charge of 8nc. Q1 In the figure above, the test charge q of charge 2. A point charge of +30HC Q, is at a distance of 60mm +20nC is 30mm from Q, (50 u C) and 20mm from from another charge Q2 with a charge of +100 JC. Q2 (6HC). Calculate: A +20 pC is placed in between the two, 25mm from Q a) The resultant electric field at that point and 35mm from Q2 . Calculate: a) The resultant electric field at this point b) The magnitude and direction of the force on the new charge b) The resultant force on the charge
