Part A) Two particles with positive charges q1 and q2 are separated by a distance s.

Along the line connecting the two charges, at what distance from the charge q1 is the total electric field from the two charges zero?

Express your answer in terms of some or all of the variables s, q1, q2 and k =14πϵ0. If your answer is difficult to enter, consider simplifying it, as it can be made relatively simple with some work.

Part B) An electric dipole is formed from two charges, ±q, spaced 1.50 cm apart. The dipole is at the origin, oriented along the y-axis. The electric field strength at the point (x,y)=(0cm,10cm) is 370 N/C.

What is the charge q? Give your answer in nC

Part C) What is the electric field strength at the point (x,y)=(10cm,0cm)?

Express your answer with the appropriate units.
