Question
Two bodies of masses 3 kg and 5 kg are connected by a
string and placed on a smooth horizontal surface. A force of 40 N is applied on the 5 kg block. What is the tension in the string?Solution
Total mass = 8 kg, acceleration = 40/8 = 5 m/s2 Tension = mass of 3 kg block × acceleration = 3. 5 =15 N
