The electric dipole moment of a water molecule (h2o) is 6.13×10−30 c⋅m. you place a water molecule in a uniform electric field of magnitude 3.00×105n/c, with the dipole moment vector at an angle of 50.0∘ from the direction of the field. calculate the magnitude of the torque on the water molecule.

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?
