$\Large\underline\mathfrak{Que stion}$

Vehicles carrying inflammable materials usually have metallic ropes touching the ground during motion.
Tell why ?

$\rule{200}{4}$

→$\bold{\boxed{\large{\boxed{\orange{\small{\boxed{\large{\red{\bold{\:ANSWER}}}}}}}}}}$

> This is done just to avoid the charging process occuring .

$\rule{200}{4}$

During motion,
The body of the vehicle gets charged due to friction of air. The tyres also accumulate the charge due to friction between the tyres and the road.

Due to charge accumulation inflammable materials inside the vehicle may catch fire.

$\rule{200}{4}$

So, to avoid this, the accumulated charge is made to flow from body to the ground through metallic ropes.
