it is scalar
it resides on the outer surface of conductor
it is non relativistic quantity

Question 4

what causes electric charge

Answer 4

it is caused by either the excess or the deficiency of electrons compared to protons

Question 5

Define Static Electricity

Answer 5

The electricity developed by bodies when they are rubbed against each other.

Question 6

Define charging by conduction

Answer 6

the method of charging a body by keeping a charged body in contact with an uncharged body

Question 7

Define Charging by induction

Answer 7

The temporary method of charging a body by bringing a charged body close to an uncharged body

Question 8

define linear charge density

Answer 8

the charge present per unit length of a conductor

Question 9

define the surface charge density

Answer 9

the charge present per unit surface area of a conductor

Question 10

define the volume charge density

Answer 10

the charge present per unit volume of a conductor

Question 11

define action of point

Answer 11

the surface charge density is high at the pointed end of a conductor

Question 12

list the uses of action of point

Answer 12

1. the action of point is used in lightning rod on buildings

2. the electrics poles supporting the transmission lines at high voltage are filled with sharp pointed conductor

Question 13

state coulomb’s law

Answer 13

It states that the force acting between two point charges is directly proportional to the square of the distance between them
