Question

A mass attached to one end of a string is travelling in a circle at constant speed. Which of the following is correct?The object’s velocity is the same as its speed.If the string breaks, the object will keep its circular motion.If the string breaks, the object will move radially away from the center of the circle.The object is accelerating as it moves.The object does not require a force to keep its state of circular motion.

Answer 1

According to problem-

Here a mass (m) attached with string moving in a circular path with constant speed. Velocity (v) is directing in direction of tangent to the circle at every point. So its direction is changing at every point.

Therefore correct option is :-

The object is accelerating as it moves.
