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

विकल्प

  •  F1 = F2

  • F1 > F2

  • F1 < F2

  •  the information is insufficient to know the relation between F1 and F2

MCQ

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.
