A uniform sphere of weight W and radius 5 ~cm is being held by a string as shown in the figure. The tension in the string will be :

Options

  1. A12 W 5
  2. B5 W 12
  3. C13 W 5
  4. D13 W 12

Correct answer

D. 13 W 12

Step-by-step solution

aligned & PQ = OP ^2+ OQ ^2 & = 13^2+5^2 =12 aligned Tension in the string T , so, T = w T = w = 13 12 ~W
