Question
The pressure in a liquid at two points in the same horizontal plane are equal. Consider an elevator accelerating upward and a car accelerating on a horizontal road. The above statement is correct in:
  1. The car only.
  2. The elevator only.
  3. Both of them.
  4. Neither of them.
✓

Answer

  1. The elevator only.

Explanation:

The two points in the same horizontal line will not have equal pressure if the liquid is accelerated horizontally. There should be vertical acceleration.
