Always had a doubt. Suppose a block is kept on top of another block which is placed on ground. All surfaces are smooth. If the lower block is moved forward with any accl, then the block above it moves bckward with respect tothe lower block. Though it is common sense but what is the real concept related to it. and what will be the accl of the above block.Eg: Q- The masses of blocks A,B,C are 1,2, and 0.5kg. All surfaces are smooth. If force F=50 N acts as shown, then find the(1) force which A exerts on B2)and the accl of C.just do and explain the 2nd part as clearly as you can
