Read the assertion and reason carefully to mark the correct option out of the options given below:
Assertion : Stress is the internal force per unit area of a body.
Reason : Rubber is less elastic than steel.
  • a)
    If both assertion and reason are true and the reason is the correct explanation of the assertion.
  • b)
    If both assertion and reason are true but reason is not the correct explanation of the assertion.
  • c)
    If assertion is true but reason is false.
  • d)
    If the assertion and reason both are false.
Correct answer is option 'B'. Can you explain this answer?

Stress is defined as internal force (restoring force) per unit area of a body. Also, rubber is less elastic than steel, because restoring force is less for rubber than steel.

Assertion: Stress is the internal force per unit area of a body.

Reason: Rubber is less elastic than steel.

The correct answer is option 'B': If both the assertion and reason are true but the reason is not the correct explanation of the assertion.

Explanation:

Stress is defined as the internal force per unit area of a body. It is a measure of the internal resistance of a material to deformation under an applied force. The formula to calculate stress is:

Stress = Force/Area

The assertion correctly defines stress as the internal force per unit area of a body. This means that stress is the force acting on a certain area of a material. It is a measure of how much force is being applied to a certain area, which determines the intensity of the internal forces within the material.

On the other hand, the reason given, "Rubber is less elastic than steel," is not directly related to the assertion. Elasticity refers to the ability of a material to regain its original shape after being deformed. It is a property that determines how much a material can stretch or compress under an applied force and then return to its original shape.

Rubber is indeed less elastic than steel, as rubber has a higher tendency to deform under an applied force and does not regain its original shape as effectively as steel. However, this does not explain the concept of stress being the internal force per unit area of a body.

The reason given is not a correct explanation of the assertion. While rubber being less elastic than steel is a valid statement, it does not provide any insight into the definition of stress. Therefore, the correct answer is option 'B': If both the assertion and reason are true but the reason is not the correct explanation of the assertion.
