A ball of mass 0.25 ~kg attached to the end of a string of length 1.96 ~m is moving in a horizontal circle. The string will break if the tension is more than 25 ~N . What is the maximum speed with which ball can be moved?

Options

  1. A14 ~m / s
  2. B3 ~m / s
  3. C3.92 ~m / s
  4. D5 ~m / s

Correct answer

A. 14 ~m / s

Step-by-step solution

Tension of string T= m v² r 25= 0.25 v² 1.96 v=14 ~m / s
