100
The strength of an electric field is determined using this equation.
What is E =Force/charge (E = F/q)?
100
This is the charge of one electron.
What is 1.60x10-19C?
100
An Electric force (F) exists between two objects, both having the charge q. If the charge on one object is doubled to 2q, the force between the objects becomes this.
What is doubled?

The SI unit for field strength (aka electric field intensity) is this.
What is Newtons per Coulomb?
200
Objects become electrically charged as a result of the transfer of these.
What are electrons?
200
Electrical and Gravitational force are similar in this way.
What is that they are both field forces?

Question 1
Answer 1
300
The strength of an electric field around a charged object depends on both of these things.
What is magnitude of the charge and the distance from the object.
300
A negatively charged rod is brought near a metal sphere that is not grounded. When the rod is taken away, the metal sphere will have this charge
What is no charge?
300
An Electric force (F) exists between two objects, both having the charge q and separated by a distance of r. if the distance is decreased to 0.5r, the force between the object will do this.
What is increase by a power of 4?
300
Question 2
Answer 2
400
This is the charge of A.
What is negative?
400
Uncharged objects can be attracted by a charged object because the uncharged objects acquire a surface charge by this process.
What is polarization through induction.
400
Two point charges initally 2 cm apartt, are moved to a distance of 8 cm apart. This is the factor that the resulting electric force between them changes.
