The effective acceleration of a body, when thrown upwards with acceleration $a$ will be
The effective acceleration of a body, when thrown upwards with acceleration $a$ will be
$\sqrt {a - {g^2}} $
$\sqrt {{a^2} + {g^2}} $
$(a - g)$
$(a + g)$
The effective acceleration of a body, when thrown upwards with acceleration $a$ will be
Net acceleration of a body when thrown upward = acceleration of body -acceleration due to gravity = $ a -g$
