As shown below, a weeder is designed with a built in pivot point. The length of the handle r2 = 31 cm. The working end r1 = 6.2 cm. If a gardener using this weeder applied a 8.70 newton of force to pull the weed. Determine the resistive force the weed exerts on this tool.

10 newton object is placed 3 meters from the fulcrum. at what distance on the other side would you need to place a 15 newton object to balance the lever? show your work!

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.
