**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.

Work done by T on m is zero because T acts along the radius and is perpendicular to the velocity (…
