Question

write true or false for the following statements

Answer 1

The answers are as follows:

1 True

• An uncharged electroscope can be charged by bringing a charged object near it without touching the electroscope. This phenomenon is called charging by induction.

2 False

• An uncharged body cannot determine the nature of the charge. The leaves of the electroscope will diverge or collapse only when the electroscope is charged.

3 True

• Lighting occurs when there is a heavy accumulation of opposite charges in two clouds. This causes a dielectric breakdown of the surrounding medium (air).

4 True

• Lighting generally strikes on taller buildings since the distance between the negatively charged clouds and the positively charged top of the building is less.

5 True

• The flow of electric current is from the negative terminal to the positive terminal while the conventional current flows from the positive to the negative terminal.
