Question

Which of the following is an effect of the electric force?

A. A positive and negative charge attract each other.
B. A positive and negative charge repel each other.
C. A North Pole and South Pole attract each other.
D. A north pole and South Pole repel each other.

Answer 1

Option A - A positive and negative charge attract each other.

Step-by-step explanation

The electric force is the result of the interaction between electric charges. An electric force is a force that exists between all charged particles. There are two types of charge, positive and negative. Like charges repel each other while unlike charges attract each other. This means that if two objects have the same charges that is positive or negative then they will repel each other. If a negatively charged particle comes in contact with a positively charged particle they will attract.

Answer 2

As we know that two charges exert force on each other when they are placed near to each other

The force between two charges is given as

`F = (kq_1q_2)/(r^2)`

here we know that

`q_1, q_2` = two different point charges

r = distance between two point charges

also we know that two similar charges always repel each other while two opposite charges always attract each other

so here correct answer would be

A. A positive and negative charge attract each other.
