Homework Statement
Consider a hellium balloon with negiligible mass in the bus with all windows closed.
When the bus is acclerating in ##\mathbf a=a \mathbf i##, where ## \mathbf i## is the unit vector in the positive x direction, describe the status of the balloon and explain the reason.
If we consider the massive balloon, does your answer change?
Explain the reason.
(Status: Does it tilt or not? What are the tilting diraction and angle?)
Homework Equations
Buoyent force ##ρgV##
The Attempt at a Solution
I know the answer might be ##tan\theta=\frac{g}{a}## or something like this, but I don't really the reason behide this.
I think it is related to physics in noninertial frames.
Any help would be appreciated.
Sincerely.
