Q- The masses of blocks A,B and C are 1,2 and 0.5kg respectively. All surfaces are smooth . If force F=50N acts as shown at the instant shown. Find the force which A exerts on b and the accl. of C. (ANS= block C will not move. my question is WHY? all sufaces are smooth. Please explain this part clearly especially with the concept of relative accl or pseudo accl and also if it has something to do with centre of mass or conservation of momentum( on block C).​2) accl of a =accl of B=50/3I did it like 50= (1+2+0.5)accl which comes out to be 100/7. Clear my concept.
