A man pulls a wagon at a 15 degree angle above the horizontal using the wagon’s handle. The man applies a force of 80 N on the wagon, which has a mass of 6.5 kg. The wagon rolls at a constant speed. Find the coefficient of friction between the wagon wheels and the ground.

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.)
