As shown in figure, the tension in the horizontal cord is 30 N . The weight w and tension in the string O A in newton are

Options

  1. A30 3 , 30
  2. B30 3 , 60
  3. C60 3 , 30
  4. DNone of the above

Correct answer

B. 30 3 , 60

Step-by-step solution

Horizontal and vertical components of tension are shown in the figure. From the figure, T sin ⁡ 30 o = 30 .....(i) T cos ⁡ 30 o = w .....(ii) By solving Equations (i) and (ii), we get w = 30 3 N and T = 60 N
