A circular disc is rotating with constant angular velocity about an axis that passes through the center. A particle '$ P$' is kept at a distance of $ 2m$ from the center and another particle '$ Q$' at a distance of $ 3m$ from the center. Which of these will have higher centripetal acceleration?
Step 1: Given data
Distance of particle from center() =
Distance of particle from center() =
Let that particle rotate in a circular motion with constant angular velocity
Step 2: Applied formulae
The centripetal acceleration is given by :
Since is constant, acceleration depends on
is the distance from the center
We know, is greater than
Therefore particle will have greater centripetal acceleration.
