A1480 kg car pulls a 360 kg trailer. the car exerts a horizontal force of 3600 n against the ground in order to accelerate. what force does the car exert on the trailer? assume an effective friction coefficient of 0.12 for the trailer. express your answer using two significant figures.

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 =14ï€ïµ0. if your answer is difficult to enter, consider simplifying it, as it can be made relatively simple with some work.
