A balloon is tied to the base of the truck with the
help of a massless string. The inclination of the
string when the truck is under forward acceleration
a is given by
(1) tano = alg (backward)
(2) tano = alg (forward)
(3) tano = g’a (backward)
(4) tano = g/a (forward)
Answer:
tano = alg ( backward )
Explanation:
because the balloon not have mass , it’s massless so it become backward .
