PRACTICAL 11 To find the tension in the strings by balancing a metre rod on the stands. VIVA VOCE 1. What is the purpose of this experiment? Ans: The purpose is to find the tension in the strings by balancing a meter rod on the stands. 2. Describe the setup of this experiment. Ans: The setup involves placing a meter rod horizontally on two stands. Strings are attached to each end of the rod, and weights are hung from the strings to create tension. 3. Why is it necessary to balance the meter rod? Ans: Balancing the meter rod ensures that the forces acting on it are in equilibrium, allowing us to accurately determine the tension in the strings. 4. How will you adjust the weights to achieve balance? Ans: We will adjust the weights on either side of the meter rod until it remains level and stationary, indicating that the tensions in the strings are balanced. 5. What factors affect the tension in the strings? Ans: The tension in the strings is affected by the weights attached
