JEE Mains · Physics · STD 12 - 2. Electric potential and capacitance
The vehicles carrying inflammable fluids usually have _______ metallic chains touching the ground.
- A To conduct excess charge due to air friction to ground and prevent sparking.
- B To alert other vehicles.
- C To protect tyres from catching dirt from ground.
- D It is a custom.
Answer & Solution
Correct Answer
(A) To conduct excess charge due to air friction to ground and prevent sparking.
Step-by-step Solution
Detailed explanation
Static charge is developed due to air friction. This can result in combustion. So, metallic chains is used to discharge excess charge.
