- Need explanation for: In general, metallic ropes are suspended on the carriers which take inflammable material. The reason is
In general, metallic ropes are suspended on the carriers which take inflammable material. The reason is
- Option 1)
There speed is controlled
- Option 2)
To keep the centre of gravity of the carrier nearer to the earth
- Option 3)
To keep the body of the carrier in contact with the earth
- Option 4)
Nothing should be placed under the carrier
Answers (2)
As we learned
Methods of charging 1. By friction -
When two bodies rub together both positive and negative charges in equal amounts appears simultaneously due to transfer of electron.
-
For providing path to charge induced on the surface of the carriers which take inflammable material
Option 1)
There speed is controlled
Option 2)
To keep the centre of gravity of the carrier nearer to the earth
Option 3)
To keep the body of the carrier in contact with the earth
Option 4)
Nothing should be placed under the carrier
JEE Main high-scoring chapters and topics
Study 40% syllabus and score up to 100% marks in JEE
Answer :- C
Option 1 says to controll speed . But for that pourpose we can use another materials, hence it is incorrect.
Option 2 says to keep center of gravity near earth . But for that we can decrease height of carrier, hence it is incorrect.
Option 3 says to keep body near earth, here due to friction of air spark can be genrate hence we use metallic wire which are connected to earth causing earthing and prevent accident, hence it is correct.
Option 4 says that nothing should place under carrier it will make spark and an accident.
