Question
Figure shows the displacement of a particle going along the X-axis as a function of time. Find the region where force acting on the particle is zero
Options
A.AB
B.BC
C.CD
D.DE
Solution
x -t curve is
(1) straight line when a = 0
(2) concave up when uniform a > 0
(3) concave down when uniform a < 0.
In the region AB & CD acceleration = 0 = Force = 0
