Electrostatic

Question 1

Types of charges that we have

Answer 1

Positive and negative charge

Question 2

How is an object positively charged or negatively charged?

Answer 2

An object is positively charged when electrons are lost and is negatively charged when electrons are gained

Question 3

What do charged electrons release?

Answer 3

They exert an electrostatic force on each other and on objects that are neutral

Question 4

Forces between charges?

Answer 4

Like charges repel and unlike charges attract

Question 5

What is an electrostatic force

Answer 5

Forces that is exerted by charged objects on other objects

Question 6

What is the unit of charge,symbol and charge if an electron?

Answer 6

Unit of charge: coulomb(C)
Symbol:Q
Charge of electrons: -1,6 × 10 to the power of negative 19
1 C= 6,25×10 to the power of 18

Question 7

3 ways in which charge can be distributed?

Answer 7

Friction
Contact
Induction

Question 8

Explain what happens at Friction?

Answer 8

When an object is rubbed with another object,electrons are physically rubbed off one object unto the other. The second object wil gain electrons and become negatively charged whereas the first object will become positively charged

Question 9

What is Triboelectric charging

Answer 9

A type of contact electrification in which certain materials become electrically charged after they came into contact with different materials and are then separated

Question 10

Explain contact

Answer 10

If a charged object touches an uncharged object they will share their charges according to their size

Question 11

What are polar molecules?

Answer 11

Molecules that have both a positive and negative side due to nature of their atoms
