With what do you divide thrust in a liquid to obtain the value of pressure?

Area

The correct answer is option 4. Area.

To obtain the value of pressure in a liquid, you divide the thrust by Area.

Pressure is defined as force per unit area. In the case of a liquid, when you divide the thrust (force) acting on the liquid by the area over which it is distributed, you obtain the pressure exerted by the liquid. This relationship is described by Pascal's law, which states that the pressure exerted at any point on a confined liquid is transmitted undiminished in all directions throughout the liquid. Therefore, the pressure in a liquid is directly proportional to the thrust or force applied and inversely proportional to the area over which the force is distributed.
