A ball tied to the end of a string swings in a vertical circle under the influence of gravity 
  • a)
    when the string makes an angle 90º with the vertical, the tangential acceleration is zero amd radial acceleration is somewhere between maximum and minimum
  • b)
    when the string makes an angle 90º with the vertical, the tangential acceleration is maximum and radial acceleration is somewhere between maximum and minimum
  • c)
    at no place in the circular motion, tangential acceleration is equal to radial acceleration
  • d)
    throughout the path whenever radial acceleration has its extreme value, the tangential acceleration is zero.    
Correct answer is option 'B,D'. Can you explain this answer?

As shown in the figure , at A 
Here, at is maximum because at other place, at = gcos θ . at and ac will be equal at some point. ac will have extreme
value at lowest points and there at = 0.

When the string makes an angle of 90 degrees with the vertical, the ball is at the highest point of its motion. At this point, the tension in the string is equal to the weight of the ball.

The tension in the string can be broken down into two components: the vertical component and the horizontal component. The vertical component of tension is equal to the weight of the ball, which is given by:

Weight = mass * acceleration due to gravity

The horizontal component of tension is zero at this point because there is no force acting horizontally.

Therefore, at the highest point of the motion, the tension in the string is equal to the weight of the ball.
