A mechanic pushes perpendicularly on the end of a 0.15m wrench. If the mechanic applies a force of 230N counter clockwise, what is the torque applied
on the bolt?

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.
