Circular Motion

AP Physics 1· difficulty 2/5

Two children pull on opposite ends of a rope, each with 200 N200~\text{N}. The rope is in equilibrium. What is the tension in the rope?

  • A

    200 N200~\text{N}

    check_circle
  • B

    100 N100~\text{N}

  • C

    00

  • D

    400 N400~\text{N}

Explanation

Tension at any cross-section equals the force pulling at either end: T=200 NT = 200~\text{N}. (You don't add the two pulls.)
