1.Consider the following statements:

1. Lightning is caused due to discharge of similar charged clouds
2. Lightning conductor always develops the opposite charges as is the charge in the clouds

Which among the above is / are correct statements?

[A] Only 1

[B] Only 2

[C] Both 1 & 2

[D] Neither 1 nor 2

How you can tell the following statement is false? Chooseone.
Lightning occurs because electrons in the ground are attracted tothe electrons in the clouds.



1) Lightning happens because the electrons in the ground arerepelled by the electrons in the clouds.
2) Lightning occurs because the electrons in the clouds areattracted to the electrons in the ground.
3) This is clearly false because clouds do not containelectrons.
4) It's not the electrons that attract each other but the protonsthat attract each other.
5) When it comes to charges, opposites attract & likes repel.Thus, electrons wouldn't be attracted to each other, they would berepelled.

If an electric field strength greater than
2.9 × 106 N/C causes the air to break down
and conduct charge (lightning), what is the
maximum charge the cloud can hold?
Answer in units of C.

If a large enough electric field is applied, even an insulator will conduct an electric current, as is evident in lightning discharges through the air. Explain how this happens at an atomic level, taking into account what a current is, the opposite charges in an atom and how ionization occurs.
