(11\%) Problem 10: Four point charges of equal magnitude $$Q=35\mathrm{nC}$$ are placed on the corners of a rectangle of sides $$D_1=16\mathrm{cm}$$ and $$D_2=I/\mathrm{cm}$$. 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 where the positive $$y$$-direction is up and the positive $$x$$-direction is to the right. $$20\%$$ Part (a) Which of the following represents a free-body diagram for the charge on the lower left hand comer of the rectangle? ? Corrost! A 20\% Part (b) Calculate the horizontal component of the net force, in newtons, on the charge which lies at the lower left comer of the rectangle. $$F_3=$$ $$\mathrm{N}$$ Hinta: 2to. deduction por hind.
