Describe how to use right-hand rules to relate the directions of magnetic fields, currents, moving charges, andforces

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?

The junction rule describes the conservation of which quantity? note that this rule applies only to circuits that are in a steady state.
