Question

(1) The two Figures below show situations in which identical masses m are hanging from massless taut strings. In Figure (1), two equal masses m are hanging from a string via a pulley at the two ends. In Figure (2), mass m is hanging from a taut string whose other end is attached to the wall. Let Tlbe the tension in string 1, and tension T2 the tension in string 2. Which of the following statements is true? Wal 1kg 1k9 2kg Figure 1 Figure 2 (a) TI> T2 (b) T2> TI (c) T1=T2 (d) The magnitude of tension in the string in Figure 1 can be either greater or smaller than that in the string in Figure 2 depending upon the actual value of the mass m (for example whether it is 0.5 kg or 1 kg etc.). (e) not enough information given (2) Justify your answer in question (1) using the appropriate laws of physics

Explanation / Answer

In figure 1 it has been mentioned that mass is of 1 kg whereas in figure 1 it has been mentioned that mass is of 2 kg.

But in the language they are saying same mass.

If both masses are same then tension will also be equal.

For figure 1 for equilibrium balancing the force for left block

T1 = mg

For figure 1

T2 = mg

So T1 = T2
