Answer 2

Answer:

The correct option is: d. A is wrong and R is correct​

Explanation:

                                   Explanation of Assertion

Pressure: Pressure is the applied force per unit area. So the formula for pressure is: Pressure = $\frac{Force}{Area}$

As area is same, so area = constant.

The expression can be, Pressure ∝ Force

That means if force is increased, then Pressure also increase. But the statement in assertion is "when force increases, pressure decreases" - this is wrong statement.

                                   Explanation of Reason

Force: Formula of force is, Force = mass × acceleration.

Mass is scalar quantity but acceleration is a vector quantity, so Force will also be a vector quantity.

A vector quantity must have direction with the magnitude. So, "Force needs both direction and magnitude for its expression" - is a correct statement.
