Q20 · Physics

A bob is whirled in a horizontal plane by means of a string with an initial speed of ω\omega rpm. The tension in the string is TT. If speed becomes 2ω2\omega while keeping the same radius, the tension in the string becomes :

  1. 1T4\frac{T}{4}
  2. 22T\sqrt{2}T
  3. 3TT
  4. 44T4TOfficial answer

Official answer: option 4 · NTA final answer key
