A lift accelerated downward with acceleration ' a '. A man in the lift throws a ball upward with acceleration `a_(0)(a_(0)lta)`. Then acceleration of ball observed by observer, which is on earth, is

A

`(a + a_(0))` upward

B

`(a -a_(0))` upward

C

`(a + a_(0))` downward

D

`(a-a_(0))` downward

Text Solution

Verified by Experts

The correct Answer is:
D
Since, `a_(0) lt a`. Hence, `a_("net") = (a-a_(0))` (downward)
