Question

A boy is running along the circumference of a stadium with constant speed. Which of the following is changing in this case?

• A. Centripetal force acting on the boy
• B. Distance covered per unit time
• C. Direction in which the boy is running
• D. Magnitude of acceleration

Answer 1

Answer: (C)

Direction in which the boy is running

Answer is C.
As the boy is running along the circumference of a stadium with constant speed, the centripetal force remains the same as it is a circular path, the distance covered and the magnitude of acceleration is same as he runs with constant speed.
Therefore, the direction in which the boy is running changes direction as the path is a circular path.
