Answer:
Option (A) is correct.
Explanation:
we need to find the the ratio of the distances traveled in the fourth and the third second by a particle, moving over a straight path with constant acceleration.
we know the formula for the distance traveled in nth second.
................(1)
we assume object starts from rest so u=0.
apply equation 1 for forth second i.e. n=4
.................(2)
apply equation 1 for third second i.e. n=3
................(3)
divide equation (2) and (3) we get,
as acceleration is constant.
So the required is (A).
