please answer the following:
Problem 3: Four point charges of equal magnitude Q-55 oC are placed on the comers of a rectangle of sides D. 19 cm and D2 - 12 cm. The charges on the left side of the rectangle are positive while the charges on the right side of the rectangle are negative. Use a coordinate system fixed to the bottom left hand charge, with positive directions as shown in the figure. +0 D21 D Part (b) Calculate the horizontal component of the net force, in newtons, on the charge which lies at the lower left corner of the rectangle Numeric : A numeric value is expected and not an expression. Part () Calculate the vertical component of the net force, in newtons, on the charge which lies at the lower left comer of the rectangle. Numeric : A numeric value is expected and not an expression. Part (d) Calculate the magnitude of the set force, in newtons, on the charge located at the lower left comer of the rectangle. Numeric : A numeric value is expected and not an expression Part (@) Calculate the angle of the net force vector relative to the +X axis, with the positive direction being counterclockwise from the positive horizontal axis. Enter an angle between - 180° and 180 Numeric : A numeric value is expected and not an expression. (Ctrl)
