You have the same line of charge in the previous problem (with +6.00 nC of charge on it).  But now you are measuring the electric field 1.5 m above the center of the rod – see image below.  Predict the electric field at Point P in this diagram.  Make sure to include a direction with your answer.

State what is meant by electric field strength at a point in space. How is its direction defined? Given that the magnitude field strength, E, at a distance r from a point charge Q is given by the formula: E = 4πεο r2 calculate the magnitude of the electric field at a point which is 10 cm from a positive 24 µC charge.
