Hint: A gum bottle is generally having a different shape for the bottle. The neck part of it will be narrow and the base is made wider. When this gum bottle is placed upside down, the narrow neck will be on the bottom part and wider base will be in the upper portion. This difference in the area of the cross section will be resulting in the variation of thrust and pressure. This will help you in answering this question.

Complete step by step answer:
A gum bottle is generally having a different shape for the bottle. The neck part of it will be narrow and the base is made wider. When this gum bottle is placed upside down, the narrow neck will be on the bottom part and wider base will be in the upper portion. When we keep the bottle upside down then the whole pressure of the bottle will be concentrated on the small surface area as compared to the previous base area. As we all know, area is found to be inversely proportional to the pressure. Because of this, in this case the bottle may be partially balanced. The area of the base will get reduced. Because of that the pressure gets increased. Therefore the force is acting perpendicularly so that this can be termed as thrust. In short, as the surface area is less at the bottom part, larger will be the effect of thrust. And also lesser the area, larger will be the pressure. Therefore the answer for the question has been found.

Note: Thrust is defined as a reaction force which has been explained using Newton's third law of motion. If a system is accelerating a mass in one direction, this accelerated mass will result in a force of identical magnitude but opposite direction on the same system. Pressure can be found by taking the ratio of the force to the surface area.
