the displacement vs time graph for A body moving in a straight line is shown in the figure which of the following regions represent the motion when no forces acting on the body. please answer it right if you know then only answer

motion along a to b is uniform motion so option a is correct in other cases motion is not uniform hence acceleration is produce and hence force is acting on the body
Naman4132:
how sir
it no force in the question
did you under my answer written above
understand
No
see when no force is acting on the body the motion is uniform and its graph will be straight line passing through the origin.
and graph a to b is straight line
but CD is also uniform see diagram
yes but the line CD did not pass through the origin
ohh ok ok

a-b = negetive acceleration,
b-c = initially negative and then positive acceleration,
c-d = no acceleration,
d-e = same as b-c
b-c = initially negative and then positive acceleration,
c-d = no acceleration,
d-e = same as b-c
