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.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F119fd9ee-0d86-405f-8fbb-1cd17cdf6dea%2F05f63028-3560-4ca4-99b9-09c88259cfc9%2Fole9l7hx_processed.jpeg&w=3840&q=75)
