Usually the force of gravity on electrons is neglected. to see why, we can compare the force of the earth’s gravity on an electron with the force exerted on the electron by an electric field of magnitude of 40000 v/m (a relatively small field). what is the force exerted on the electron by an electric field of magnitude of 40000 v/m? the acceleration of gravity is 9.8 m/s 2 , the mass of an electron is 9.10939 × 10−31 kg, and the elementary charge 1.602 × 10−19 c. answer in units of n.

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?
