Question

For a particle in uniform circular motion the acceleration a at a point P(R,θ)
on the circle of radius R is (Here , θ is measured from the x - axis)

[AIEEE 2010] ​

Answer 1

Explanation :- For a particle in uniform circular motion .

• a = v²/R(Towards centre of Circle)
• a = v²/R ( - cos¢ i - sin¢ j )
• ∴ [centriputal acceleration ]
• a = -v²/R cos¢i - v²/R sin¢ j Answer
