two blocks each of mass 3 kg are connected by a light cord and placed on a rough horizontal surface when a horizontal force of 20N is applied on a block an acceleration of 0.50metre per second square is produced in each block find tension in string and frictional force which is same in two blocks

Answer : taking whole as a system - 20-2F =6 ×a and a= 0.5 m/s square . then , 2f =20 -6×0.5 f =17/2=8 .5 is frictional force on each block then, on block B , T-F =3 ×a = T= 3×0.5 +F = 1.5 +8.5 and , T =10
