Question: A conical pendulum swings in a horizontal circle. If the angle of the string with the vertical increases, what happens to the tension in the string?

Options:

  1. Increases
  2. Decreases
  3. Remains the same
  4. Becomes zero

Correct Answer: Increases

Solution: 

As the angle increases, the vertical component of tension must increase to balance the weight.

Questions & Step-by-Step Solutions

A conical pendulum swings in a horizontal circle. If the angle of the string with the vertical increases, what happens to the tension in the string?
  • Step 1: Understand that a conical pendulum swings in a circle while the string makes an angle with the vertical.
  • Step 2: Recognize that the pendulum has two forces acting on it: the tension in the string and the weight of the pendulum (gravity).
  • Step 3: When the angle of the string with the vertical increases, the pendulum moves further away from the vertical position.
  • Step 4: Realize that the weight of the pendulum (downward force) remains constant, but the way tension acts changes with the angle.
  • Step 5: The tension in the string has two components: a vertical component that balances the weight and a horizontal component that provides the centripetal force for circular motion.
  • Step 6: As the angle increases, the vertical component of the tension must increase to continue balancing the weight of the pendulum.
  • Step 7: Therefore, as the angle increases, the overall tension in the string must also increase.
  • Forces in a Conical Pendulum – Understanding the balance of forces acting on a conical pendulum, including tension and gravitational force.
  • Components of Tension – Analyzing how the tension in the string can be broken down into vertical and horizontal components.
  • Centripetal Force – Recognizing the role of tension in providing the necessary centripetal force for circular motion.
