Two bodies of masses 10 kg and 20 kg respectively kept on a smooth, horizontal surface are tied to the ends of a light string. A horizontal force F = 600 N is applied to (i) A, (ii) B along the direction of string. What is the tension in the string in each case?

Explanation

If the 20 kg mass is pulled, 600 – T = 20 a, T = 10 a
` a = 20 ms^(-2)` T = 200N
If the 10 kg mass is pulled , ` a = 20 ms^(-2)` , T = 400N
