electric fields

Question 1

explain the concept of an electric field.

Answer 1

like magnetic fields for magnets, electric fields are for charges
o They point in the direction a positive charge would go i.e. away from positive
charges, and towards negative charges.
o They point to charges at right angles to the surface

Question 2

what is the rule of electric fields

Answer 2

Stronger the charge, the more field lines present and the stronger the force felt
- Closer to the charge, the stronger the force felt

Question 3

electric field diagrams

Answer 3

Question 4

describe what happens to a second charged object placed in the electric field created around the initial
charged object.

Answer 4

it experiences a non-contact electrostatic force. This force causes the second object to move either toward or away from the initial object, depending on the types of charge involved

Question 5

describe how the strength of an electric field around a charged object varies with distance from the object.

Answer 5

Strongest Near the Surface: The electric field strength is highest closest to the charged object.
Decreases with Distance: As you move further away from the charged object, the strength of the electric field decreases.
Inverse Relationship: The force experienced by another charged object placed in the field gets weaker as the distance increases

Question 6

explain how the concept of an electric field helps to explain the non-contact force between charged objects as
well as other electrostatic phenomena such as sparking.

Answer 6

The strength increases closer to the object, defined by field lines pointing away from positive or toward negative charges. Strong fields can ionize air, making it conductive and causing sparking
