As shown above an adhesive has been applied to contacting faces of two blocks so that the blocks interact with an adhesive force that has a magnitude, Fadhesion. A tension, T, is exerted by a wire attached to the upper blocks causing the blocks to remain at rest. The two blocks have weights, Wbottom  and Wtop. Which of the following must be true?   Wtop=T Wbottom=Fadhesion T=Wtop−Fadhesion T=Wbottom+Wtop+Fadhesion
