Assertion: If an object is submerged in fluid at rest, the fluid exerts a force on its surface.
Reason: The force exerted by the fluid at rest has to be parallel to the surface in contact with it.

A

Both assertion and reason are true and reason is the correct explanation of assertion.

B

Both assertion and reason are true but reason is not the correct explanation of assertion.

C

Assertion is true and reason is false.

D

The correct Answer is:
To solve the question, we need to analyze both the assertion and the reason given. ### Step-by-step Solution: 1. **Understanding the Assertion**: - The assertion states that if an object is submerged in a fluid at rest, the fluid exerts a force on its surface. - This is true. When an object is submerged in a fluid, the fluid molecules collide with the surface of the object, exerting a force due to pressure. 2. **Understanding the Reason**: - The reason states that the force exerted by the fluid at rest has to be parallel to the surface in contact with it. - This is false. The force exerted by the fluid is due to pressure, which acts perpendicular to the surface of the object. Pressure is defined as force per unit area, and the force vector is always directed normal (perpendicular) to the surface. 3. **Conclusion**: - Since the assertion is true and the reason is false, the correct answer is that the assertion is true, but the reason is false. ### Final Answer: - The assertion is true, and the reason is false. Therefore, the correct option is C. ---
