In the hydrogen atom we find that the electrical force between the
electron and proton is almost 1040 times greater than the
gravitational force. Is there a finite distance between
the particles such that the electrical force equals the gravitational force?
A. Yes, if we move them much closer together.
B. Yes, if we move them much farther apart.
C. No, because the electrical and gravitational forces have the same
distance dependence.
An electric dipole is placed at +/- x0 on the x-axis
as shown below. What will be the direction of the resultant electric field
at point P on the y-axis?
