(a) calculate ffs f fn ds for the function in problem ii-14(a) over the surface of a cube of side s whose center is at (xo» vo, zo) and whose faces are parallel to the coordinate planes. (b) divide the above result by the volume of the cube and cal- culate the nimit of the quotient as s -»0. compare your result with the divergence found in problem ii-14(a) (c) repeat parts (a) and (b) for the function of problem ii-14(b) and (c) (a) ir jykz? .

Balloon a has charge q, and identical mass balloon b has charge 10q. you hang them from threads near each other. choose all of the statements with which you agree. check all that apply. a. a and b exert the same magnitude forces on each other. b. the force that a exerts on b is 10 times the force that b exerts on a. c. the angle between the thread supporting a and the vertical is < the angle between the thread supporting b and the vertical. d. the force that a exerts on b is 1/10 the force that b exerts on a.
