A body of mass 60 ~kg is suspended by means of three strings P, Q and R as shown in the figure is in equilibrium. The tension in the string P is

Options

  1. A130.9 ~g ~N
  2. B60 gN
  3. C50 ~g ~N
  4. D103.9 ~g ~N

Correct answer

D. 103.9 ~g ~N

Step-by-step solution

R 60^ =Q=60 ~g ^ 60 ~g aligned & R= 60 ~g 60^ =120 ~g & P=R 60^ =120 ~g 3 2 =103.9 ~g ~N aligned
