Two boxes are on opposite ends of a plank that is 3.0 m long. the plank is supported in the middle by a fulcrum. the box on the left has a mass, m1, of 25 kg. the box on the right has a mass, m2, of 15 kg. use the formulas below to determine how far the fulcrum must be positioned from the right side of the plank in order to balance the masses horizontally. (hint: g=9.8m/s2

Large electric fields in cell membranes cause ions to move through the cell wall. the field strength in a typical membrane is 1.0 x 10 7 n/c. what is the magnitude of the force on a calcium ion with charge +e? what is its acceleration? is it possible for a particle with the same charge as as calcium to have a different acceleration if placed at this location? what would change the acceleration: mass of the particle? diameter of the particle?
