Knowledge Check: String in a Circle Please answer the following question(s): 1. Object of mass m tied at the end of a string of length R whirled around a circle. The tension in the string is T. How much work does T do on the object? T Work done by T on m is Centripetal force R 2 because, T acts along the radius and is to the velocity (instantaneous displacement) which is along the tangent. do work on the object during circular motion.

Question
**Knowledge Check: String in a Circle**

Please answer the following question(s):

1. Object of mass *m* tied at the end of a string of length *R* whirled around a circle. The tension in the string is *T*. How much work does *T* do on the object?

   ![Diagram of object whirling in a circle](https://via.placeholder.com/150)

   - Diagram Explanation:
     - A circle with radius *R*.
     - A point object on the circumference, connected via a string.
     - The string represents tension *T* acting towards the center.
     - The velocity *v* of the object is tangent to the circle.

   Work done by *T* on *m* is [Blank] because *T* acts along the radius and is [Blank] to the velocity (instantaneous displacement) which is along the tangent.

   Centripetal force [Blank] do work on the object during circular motion.
