What is the net force exerted by these two charges on a third charge q3 = 48.0 nc placed between q1 and q2 at x3 = -1.050 m ? your answer may be positive or negative, depending on the direction of the force.

Aprotein molecule in an electrophoresis gel has a negative charge. the exact charge depends on the ph of the solution, but 30 excess electrons is typical. what is the magnitude of the electric force on a protein with this charge in a 1600n/c electric field? write in two significant numbers, and also in newton
