Q. Charge of -3.30 nC and a charge of -6.25 nC are separated by a distance of 40.0 cm. Find the position at which a third charge of +7.60 nC can be placed so that the net electrostatic force on it is zero.
Q. If the charge of the point charge in the figure were -4Q (instead of +Q), by what factor would the magnitude of the force on the point charge due to the dipole change?
Would the direction of the force change?a)The force would be in the opposite direction.b)The direction of the force would stay the same.
