Question
**Transcription for Educational Website** **Problem Statement:** A ball of mass \( m \) is attached to a thin string and whirled in a vertical circle of radius \( r \). The magnitude of the tension in the string at point \( e \) where the ball is moving with speed \( v \) is: **Diagram Explanation:** The diagram depicts a vertical circle with labeled positions \( a, b, c, d, e, \) and \( f \) along the circle. The radius of the circle is denoted by \( r \). At point \( b \), the ball is shown moving in the direction of the tension vector. The circle with these points represents the path of the ball attached to a string. The point \( e \) is one of the positions along this circular path where the tension needs to be calculated. **Answer Choices:** - \( \frac{mv^2}{r} \) - \( \frac{mv^2}{r} - mg \) - \( mg \) - \( mg + \frac{mv^2}{r} \) - \( mg \cos(\theta) \) The problem asks for the magnitude of the tension in the string at point \( e \) as the ball moves along its circular path. Select the correct expression from the given options.
