How does pressure exerted by solid and a fluid differ?A. A solids exert pressure only on its base downwards while a fluid exerts pressure at all points in every direction.B. A liquid exerts pressure only on its base downwards while a solid exerts pressure at all points in every direction.C. Both exerts pressure on its base downward.D. Both exerts pressure at all points in all directions.

1. Pressure in Solids:
o A solid object applies pressure on its base or the surface it is in contact with, typically in the downward direction due to gravity. The pressure exerted by solids is typically localized where the object is in contact with other surfaces, and it is generally applied perpendicular to the surface.
2. Pressure in Fluids:
o Fluids (liquids and gases) behave differently from solids. In a fluid, pressure is exerted at all points within the fluid, and this pressure acts in all directions, not just downward. Fluid molecules are free to move, and due to the random motion of molecules in the fluid, they exert force equally in all directions. This is why fluids are able to exert pressure on the sides of their containers and in any direction within the fluid itself.
Conclusion:
• A solid primarily exerts pressure downward on its base, whereas a fluid exerts pressure in all directions and at all points within the fluid. This is a key difference between the behavior of solids and fluids under pressure.
Thus, the correct answer is: A) A solid exerts pressure only on its base downwards while a fluid exerts pressure at all points in every direction.
