Solution

The correct option is A
Attract the positive charges to the surface, and cause them to accumulate

When lightning strikes the Earth, it is because there is a build-up of negative charges at the bottom of the cloud and positive charges at the ground surface. This causes the negatively charged cloud to induce positive charges to accumulate on the ground. This is charging by induction. The negative charges attract the opposite (positive) charges.

Why is it that all like charges repel and unlike charges attract?

What causes them to do so?

Q. Statement 1: The positive charges collect near the upper edges of the clouds and the negative charges accumulate near the lower edges.
Statement 2: The charge separation is caused due to vigorous upward movement of air currents and the downward movement of water droplets.

The clouds consist of charged particles of water dispersed in the air. Some of them are positively charged, others are negatively charged. When positively charged clouds come closer, they cause lightning and thundering whereas when positive and negative charged colloids come closer, they cause heavy rain by aggregation of minute particles. It is possible to cause artificial rain by throwing electrified sand or silver iodide from an aeroplane and thus, coagulation the mist hanging in the air.

Which of the following statements is/are false?

a. Lightning is an electric spark on a huge scale which is caused by the accumulation of electric charges in the clouds.
b. Electric charge is the property of matter which is responsible for the electrical phenomenon.
c. The electric charges which appear on a plastic comb when rubbed with dry hair are the static electric charges which remain bound to the surface of an object and do not move.

Q. Due to charging by friction, negatively charged particles accumulate at the bottom of clouds.
