MCQ
A body is projected vertically upward direction from the surface of earth. If upward direction is taken as positive, then acceleration of body during its upward and downyard jourhey are respectively
  • A
    Positive, negative
  • ✓
    Negative, negative
  • C
    Positive, positive
  • D
    Negative, positive
✓

Answer

Correct option: B.
Negative, negative
b
(b)

Whether body move upwards or downwards the earth tries to pull it downwards only. Hence during both the motion $g$ will negative?

So, negative, negative
