A mass ' M ' is suspended by a rope from a rigid support at point ' P ' as shown in figure. Another rope is tied at end 'Q' and pulled horizontally with a force ' F '. If the rope makes an angle ' ' with vertical then the tension in the string ' PQ ' is

Options

  1. AF
  2. BF
  3. CF
  4. DF

Correct answer

B. F

Step-by-step solution

Tension in the string PQ is determined by analyzing the equilibrium conditions at point Q where the ropes meet. The horizontal tension component balances the applied force F , while the vertical component supports the weight Mg . Resolving the tension T into components: Vertical component: T Horizontal component: T From horizontal equilibrium: T = F Solving for tension: T = F This corresponds to option B.
