Question

vehicles carrying inflammable materials usually have metallic ropes touching the ground during motion. Why?

Answer 1

Answer:

Vehicles carrying inflammable materials usually have metallic ropes touching the ground during the motion of the vehicle because the body of the vehicle in motion is charged due to air friction.

If the charge accumulation is large, it can produce a spark and the inflammable material may catch fire.

To prevent this mis-happening metallic ropes are hung so that any charge accumulated on the vehicle leaks to the earth.

Answer 2

Explanation:

Yes

♥ Due to the friction of air , the body of the vehicle also get charged in addition to the charge developed on tyres

♥ If the charge accumulation becomes large it may destroy the vehicle by carrying inflammable materials

♥ so the metallic ropes in the vehicle are made to touch the ground so the charge on the vehicle leaks to the earth.

♥ if they remain in contact with ground the charge flows to earth through the loq resistance path
