[Solved] The rubber used in the wheels of aero-plane is _________

The rubber used in the wheels of aero-plane is _________

a) Perfect insulator
b) Slightly conducting
c) Can be an insulator or conducting
d) Semiconductor

Answer: b
Explanation: Due to high friction during takeoff, a huge amount of charge is produced on the rubber of the wheel of a plane. This charge must be sent to the ground. So, the rubber used is slightly conducting, else the huge charge produced may produce a spark and can cause an accident.
