A square Lamina OABC of length 10 cm is pivoted at 'O'. Forces act at Lamina as shown in figure. If Lamina remains stationary, then the magnitude of F is :

Options

  1. A20 N
  2. B0 (zero)
  3. C10 N
  4. D10 2 ~N

Correct answer

C. 10 N

Step-by-step solution

Since the lamina is equilibrium. F _ net =0 & _ net =0 T _ o =10 - F F =10 ~N
