Question

Three identical uniform rods are hinged on a wall,while their other ends are attached to a wall by three mass less strings as shown in diagram:

• A. Tension in strings (ii) and (iii) are same.
• B. Tension in strings (i) and (ii) are same.
• C. Tension in all strings are same.
• D. Tension are different in all strings.

Answer 1

The correct option is C Tension in all strings are same.

$\begin{array}{c}\text{Correct option is}\left(c\right)\\ \text{As their is no change in the inclination}\\ \left(\theta \right)\text{of rod with the vertical.}\\ \text{Hence, Tension in all strings are same}\\ \text{because only gravitational force is balanced}\\ \text{through tension which is same in all}\\ \text{the cases.}\end{array}$
