A light string passes over a frictionless pulley. To one of its ends a mass of $6\, kg$ is attached. To its other end a mass of $10\, kg$ is attached. The tension in the thread will be ........ $N$
$T = \frac{{2{m_1}{m_2}}}{{{m_1} + {m_2}}}g = \frac{{2 \times 10 \times 6}}{{10 + 6}} \times 9.8 = 73.5N$
