प्रश्न
Consider the situation of the previous problem. Let the water push the left wall by a force F1 and the right wall by a force F2.
पर्याय
F1 = F2
F1 > F2
F1 < F2
the information is insufficient to know the relation between F1 and F2
Advertisements
उत्तर
F1 > F2
When the box is accelerated towards right, the water in the box experiences a pseudo force (ma) towards left, where m is the mass of water. So, the force F1 exerted by the water on the the left wall of the box is greater.
