UPSC 2004: A spherical body moves with a uniform angular velocity ω around a circular path of radius r. Which one of the following statements is correct?
(a)The body has no acceleration
(b)The body has a radial acceleration ω²r directed towards the centre of the path
(c)The body has a radial acceleration 2/5 ω²r directed away from the centre of the path
(d)The body has an acceleration ω²r tangential to its path
Attempt This Question
Not attemptedCorrect Answer: (b) The body has a radial acceleration ω²r directed towards the centre of the path
In uniform circular motion a body experiences centripetal (radial) acceleration a = ω²r directed toward the centre of the circle; none of the tangential or outward accelerations given are correct. Therefore option (b) is right. ([licchavilyceum.com](https://licchavilyceum.com/upsc-civil-services-prelims-2004-solved-question-paper/))
