Four point charges, two positive charges on the x-axis and two negative charges on the y- axis, , are located at a distance a = 6.5 cm from the origin on either side of it. The charge of each of them is q = 3 C or -3 C Another positive point charge, with charge Q = 123 C, is located at point P on the positive x-axis a distance b = 1.1 m to the right of the rightmost positive charge. Refer to the figure. x-axis y-axis A b 25% Part (a) Enter an expression for the x-component of the force on the point charge, in terms of defined quantities and the Coulomb constant k, at P due to the negative charges. A 25% Part (b) Enter an expression for the x-component of the force on the point charge at P due to the nearest positive charge, in terms of defined quantities and the Coulomb constant k. 25% Part (c) Enter an expression for the x-component of the force on the point charge at P due to the farthest positive charge, in terms of defined quantities and the Coulomb constant k. 25% Part (d) Calculate the x-component of the net force, in newtons, acting on the point charge at P.
