Assertion (A): A simple carburettor which is set to give a correct mixture at low air speeds will give a progressively rich mixture as the air speed is increased. 
Reason (R): As the pressure difference over the jet of a simple carburettor increases the weight of petrol discharge increases at a greater rate than does the air supply.
  • a)
    Both A and R are individually true and R is the correct explanation of A
  • b)
    Both A and R are individually true but R is not the correct explanation of A
  • c)
    A is true but R is false
  • d)
    A is false but R is true
Correct answer is option 'A'. Can you explain this answer?

Assertion (A): A simple carburettor which is set to give a correct mix...
Explanation:

Assertion (A):
- The statement is true because at low air speeds, a simple carburettor is set to provide a correct mixture of air and fuel.
- However, as the air speed increases, the pressure difference over the jet of the carburettor also increases, leading to a richer mixture being delivered.

Reason (R):
- The reason is true because as the pressure difference over the jet increases, the weight of petrol discharge also increases.
- The rate at which the weight of petrol discharge increases is greater than the rate at which the air supply increases, resulting in a progressively rich mixture.
Therefore, both Assertion (A) and Reason (R) are individually true, and Reason (R) is the correct explanation of Assertion (A).
