Which statement about velocity is true A.it has only magnitude

1) 2.56 x 10^ -17 n away from each other. as it is the force between two electrons, it is a repulsive force. the magnitude of the force is given by f = q1q2/(4*pi*e*r^2) where q1 q2 are the two charges interacting, e is the permitivitty of free space, and r is the distance between the charges. substituting our values, we have f = (1.6 x 10^-19)^2/(4*pi*e*3.00 x 10^-6)^2 = 2.56 x 10^-17 n.
