A body is projected vertically upward from the surface of earth. If upward direction is
taken as positive, then acceleration of body during its upward and downward journey are respectively:
Text Solution
Verified by ExpertsThe correct answer is:
B
When body is moving up and down the gravitational force or g is acting on the body in only
one direction i.e. downward so the acceleration is - ve. we are considering the upward direction as + ve, then the opposite direction, that is, downward direction is taken as - ve.
