Physics Two Dimensional Motion Question 259
Question: A body is revolving with a constant speed along a circle. If its direction of motion is reversed but the speed remains the same, then which of the following statement is true
Options:
A) The centripetal force will not suffer any change in magnitude
B) The centripetal force will have its direction reversed
C) The centripetal force will not suffer any change in direction
D) The centripetal force would be doubled
Show Answer
Answer:
Correct Answer: A
Solution:
Centripetal force = $ \frac{mv^{2}}{r} $ and is directed always towards the centre of circle. Sense of rotation does not affect magnitude and direction of this centripetal force.
