Positive charge +Q is distributed uniformly along the +x-axis from x = 0 to x = a. Negative charge -Q is distributed uniformly along the -x axis for x = 0 to x= -a. A positive point change q lies on the positive y-axis, a distance y(y»a) from the origin. If the net force applied by the positive and negative charge distribution on the point charge q is F, if F = Cy⁻ᴷ Newton, where C is positive constant. then find the value of K.
