Electrostatics

Question 1

What is electrostatics

Answer 1

The study of static electricity/charges at rest

Question 2

What happens when the same amount of positive and negative charges in an object are brought together

Answer 2

They neutralize each other so there is no nett charge

Question 3

When can we say an object is electrically charged

Answer 3

When a little more of one charge is present in an object

Question 4

What is tribo electrical charge

Answer 4

When two objects come into contact with one another and are then separated from each other, one gains electrons and obtains a negative charge and the other loses electrons gaining a positive charge

Question 5

What is polarization

Answer 5

Attraction between charged and uncharted objects

Question 6

What is a temporary dipole

Answer 6

When each molecule of an object has a positive and negative pole

Question 7

What is induced polarization

Answer 7

When polarization takes place due to the proximity of an external charge (not permanent)

Question 8

Describe the polarization of water molecules

Answer 8

Water molecules are polarized naturally. Oxygen atoms have stronger electrostatic forces than hydrogen. Oxygen’s side is slightly negative and the hydrogen atoms are slightly positive.
It is a permanent dipole. The molecule is neutral but electrons are arranged in an uneven manner

Question 9

What is the law of conservation of electric charge

Answer 9

Charge is neither created nor destroyed, it is only transferred from one object to another

Question 10

What is the principle of quantization of charge

Answer 10

An object has an electrical charge that is an integer multiple of the elementary charge (electron charge)
