How does the amount of energy required to hold each proton and neutron in the nucleus compare to the energy released when they are removed?

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?

What is the magnitude of the gravitational force acting on the earth due to the sun?
