1.	Three blocks of masses m_(1), m_(2) and m_(3) are connected by a massless string as shown in figure on a frictionless table. They are pulled with a force T_(3) = 40N. If m_(1) = 10kg, m_(2) = 6kg and m_(3) = 4kg,then tension T_(2) will be
Answer» 10 N 20 N 32 N 40N Solution :`F_("NET")=ma, T_(3)-T_(2)=m_(3)a, T_(2)-T_(1)=m_(2)a, T_(1)=m_(1)a` Solving the above equations, we GET
