Question

A balloon is massless when it is empty and its thickness is almost zero. The ballon is tightly inflated with air and left hanging in a car. The car starts moving ahead with acceleration 'a' then in the frame of the car(at equilibrium state)

• A. The balloon will move forward
• B. The balloon will move backward
• C. The balloon will be at the same position
• D. The ballon can move in any direction

Answer 1

The correct option is B The balloon will move backward

When observed w.r.t. car, which is accelerating i.e., Non- Inertial frame and a pseudo force will be applied in the backward direction. Hence, The balloon will move backwards
