Aeroplane Tyre Electrification – Rankers Physics

Properties of Charges: Practice Problem & Solution

Assertion (A): The tyres of aeroplanes are slightly conducting. Reason (R): During take off and landing of aeroplanes, the friction between tyres and the runway may cause electrification of tyres.  
Both (A) & (R) are true and the (R) is the correct explanation of the (A)
Both (A) & (R) are true but the (R) is not the correct explanation of the (A)
(A) is true but (R) is false
Both (A) and (R) are false

Short Solution (Best for NEET):

To solve this problem, we apply the core principles of Properties of Charges. Understanding the underlying formula is key to arriving at the correct answer below:

Assertion (A) is true: Conducting tyres prevent hazardous static charge accumulation. Reason (R) is true: Friction during takeoff and landing causes static electrification.

(R) correctly explains (A) because the conducting tyres allow the generated static charge to safely discharge into the runway, preventing sparks and potential ignitions.
