(B) Let $m_1 = 1\, kg$ and $m_2 = 5\, kg$. The tension $T$ in the string is given by the formula:$T = \frac{2 m_1 m_2}{m_1 + m_2} g = \frac{2 	imes 1 	imes 5}{1 + 5} g = \frac{10}{6} g = \frac{5}{3} g$The spring balance measures the total downward force exerted by the pulley system,which is equal to the sum of the tensions in the two segments of the string pulling downwards on the pulley. Thus,the reading $R$ is:$R = 2T = 2 	imes \left( \frac{5}{3} g ight) = \frac{10}{3} g$Since the spring balance is calibrated to read in $kg$ (where $1\, kg$ corresponds to a force of $g$),the reading in $kg$ is:$R_{kg} = \frac{10}{3} \approx 3.33\, kg$Since $3.33\, kg < 6\, kg$,the reading of the spring balance will be less than $6\, kg$.

Two masses of $1\, kg$ and $5\, kg$ are attached to the ends of a massless string passing over a pulley of negligible weight. The pulley itself is attached to a light spring balance as shown in the figure. When the masses are released and start moving,the reading of the spring balance will be:

One end of a string of length $l$ is connected to a particle of mass $m$ and the other to a small peg on a smooth horizontal table. If the particle moves in a circle with speed $v$,the net force on the particle (directed towards the centre) is ($T$ is the tension in the string).

Three blocks of masses $4\,kg$,$6\,kg$ and $8\,kg$ are hanging over a fixed pulley as shown. The tension in the string connecting the $8\,kg$ and $4\,kg$ blocks is:

$A$ body of weight $200 \,N$ is suspended from a tree branch through a chain of mass $10 \,kg$. The branch pulls the chain by a force equal to (if $g=10 \,m/s^2$): (in $\,N$)
