NEET Physics Pressure in Fluids Assertion Reason Question
Assertion (A): The pressure difference between the lower and upper surfaces of an aircraft's wings is crucial for flight. | Reason (R): Pressure difference causes a lift force that balances the aircraft's weight.
Both A and R are true and R is the correct explanation of A.
Both A and R are true but R is not the correct explanation of A.
A is true but R is false.
A is false.
Correct Answer
Detailed Explanation
The assertion is true as the pressure difference is necessary for lift, which is explained by the reason; the weight of the aircraft is balanced by the upward force due to this pressure difference.
