Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which is true
A
In a static liquid at same horizontal level, pressure is more at centre
B
In a static liquid at same horizontal level, pressure is less at centre
C
In a static liquid at same horizontal level, pressure is same at all points
D
In a static liquid at same horizontal level, pressure is different at all points
Explanation: 

Detailed explanation-1: -In a liquid at same level the pressure will be same at all points, if not due to pressure difference the liquid cannot be at rest. This is why the height of liquid is the same in vessels of different shape containing different amounts the same liquid at rest when they are in communication with each other.

Detailed explanation-2: -Hence, the given statement is true.

Detailed explanation-3: -The pressure at any two points at the same level in a liquid is the same since the depth below the surface is the same. Since the pressure at all points at the same depth is the same it follows that that the pressure at a point is the same in all directions.

Detailed explanation-4: -Since weight is the downward force, it will allow pressure to be the same. If one side has a higher water level than the other, then it will have higher pressure.

Detailed explanation-5: -Pascal’s law states that an increase in pressure at any point inside a liquid at rest is transmitted equally and without any change, in all directions to every other point in the liquid.
