question

When a ball at rest hangs by a single vertical string tension in the string is mg. If the ball is made to move in amhorizontal circle so that the string describes a cone string tension

category

physics

options

  1. may be equal to mg depending on the speed of the ball
  2. is mg
  3. is less than mg when the ball is at the highest point in the circle
  4. is greater than mg always
  5. is equal to the square of the speed of the ball
  6. remains unchanged regardless of the movement of the ball
  7. is inversely proportional to the speed of the ball
  8. is less than mg always
  9. is directly proportional to the speed of the ball
  10. may be greater or less than mg depending on the speed of the ball
