A particle is moving along an elliptical path with constant speed. As it moves from A to B, magnitude of its acceleration :

Options

A. Continuously increases
B. continuously decreases
C. Remains constant
D. first increases and then decreases

Explanation

`a_(t)=(dv)/(dt)=0`
`a_(c)=(v^(2))/R`
From A to B radius of curvature increases
So, acceleration decreases
