A 36 kg girl and a 9.7 kg sled are on the frictionless ice of a frozen lake, 19 m apart but connected by a rope of negligible mass. The girl exerts a horizontal 5.8 N force on the rope. What are the acceleration magnitudes of (a) the sled and (b) the girl? (c) How far from the girl's initial position do they meet?

a charge 3q is at the origin, and a charge −2q is on the positive x axis at x=a. part a where on the x-axis would you place a third charge so it would experience no net electric force? enter an expression for the exact answer, which will involve a square-root sign. (do not enter an approximate decimal answer.)
