Question

P, Q and R are three identical blocks resting on a smooth surface. A force of 30 N is applied at one end as shown in the diagram. What are the tensions Ti, between blocks P and Q, and T2, between blocks Q and R, in the strings? T T2 Р Q R 30 N T2 15 N T (a) 15 N b) 30 N (c) 20 N (d) 10​

Answer 1

Answer:

first find the accleration of the whole system then you can easily get the tension

Answer 2

Answer:

The correct answer is  (a) 15 N

Explanation:

From the above question,

They have given :

The tensions in the strings Ti, between blocks P and Q, and T2, between blocks Q and R, can be determined using the idea of equilibrium. This states that in an equilibrium system, the sum of all the forces must be equal to zero.

In this case, the forces acting on the blocks are the tension in the strings and the force of 30 N applied at one end. The tensions in the strings must be equal and opposite in order to maintain equilibrium.

Therefore, the tension in both strings is equal to 15 N. The tension between blocks P and Q (Ti) is 15 N and the tension between blocks Q and R (T2) is also 15 N.

Thus,

     The correct answer is  (a) 15 N
