All the surfaces and pulleys are frictionless in the shown arrangement. Pulleys $$P$$ and $$Q$$ are massless. The force applied by clamp on pulley $$P$$ is
  • A
    $$\dfrac {mg}{6}(-\sqrt {3}\hat i-3\hat j)$$
  • B
    $$\dfrac {mg}{6}(\sqrt {3}\hat i+3\hat j)$$
  • C
    $$\dfrac {mg}{6}\sqrt {2}$$
  • D
    $$None\ of\ the\ above$$

Solution
