NEETPhysicsElectrostatics
Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A) : The tyres of aircrafts are slightly conducting. Reason (R) : If a conductor is connected to ground, the extra charge induced on conductor will flow to ground. In the light of the above statements, choose the most appropriate answer from the options given below:
Options
- ABoth (A) and (R) are true and (R) is the correct explanation of (A).
- BBoth (A) and (R) are true and (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
A. Both (A) and (R) are true and (R) is the correct explanation of (A).
Step-by-step solution
Assertion (A): The tyres of aircraft are slightly conducting. - This is true. Aircraft tyres are designed to be slightly conductive to allow static electricity to dissipate safely to the ground when the aircraft lands. Reason (R): If a conductor is connected to ground, the extra charge induced on the conductor will flow to the ground. - This is true. When a conductor is grounded, any excess charge (positive or negative) will flow to or from the ground, neutralizing the conductor.
