After factoring in all the electrons and protons in a water molecule, the electric field has the mathematical patterned given by the formula: E 3.6 x 10-20 r3 where E is the electric field measured in N/C and r is the distance from the water molecule measured in meters. What is the magnitude of the change in electric potential for an object (say sodium atom) that moves from close (r = 4.00 x 10^-9 m) to the atom to far away (125 x 10^-9 m)?
