Vehicles carrying inflammable materials usually have metallic ropes touching the ground during motion. Why?
1 Answer
Saurabh Koranglekar
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.

The length of a massless rod is measured using vernier callipers having 10 vernier scale divisions and least count of 0.1 mm. Two masses 1.00 ± 0.01 kg and 4.00 ± 0.02 kg are attached to its ends. If reading of vernier scale is 5 divisions coinciding with 1.3 cm, what is the % error in locating centre of mass from lighter mass
