A bar of uniform cross section and weighing $100 \:N$ is held horizontally using two massless and inextensible strings $S1$ and $S2$ as shown in the figure
The tensions in the strings are
- $T_1=100 \: N \text{ and } T_2=0 \: N$
- $T_1=0 \: N \text{ and } T_2=100 \: N$
- $T_1=75 \: N \text{ and } T_2=25 \: N$
- $T_1=25 \: N \text{ and } T_2=75 \: N$
