Electric Fields

Question 1

electric field strength

Answer 1

efs of an electric field at a point in space is the force experienced per unit positive charge at that point.

Question 2

electric potential

Answer 2

the work done per unit charge against the field to move a positive point charge from infinity to that point.

Question 3

electric field equation and unit

Answer 3

E = F/Q (N/C)

Question 4

which way do electric fields point

Answer 4

positive to negative

Question 5

coulombs law

Answer 5

any 2 point charges exert an electrostatic force on each other that is directly proportional to the product of their charges and inversely proportional to the square of the distance between them.

Question 6

g v e property that creates the field

Answer 6

g - mass
e - charge

Question 7

g v e type of field produced

Answer 7

g - attractive
e - positive point charges produce a repulsive field/ negative point charges produce attractive

Question 8

g v e field strength

Answer 8

g - force per unit mass g =f/m
e - force per unit positive charge e =f/q

Question 9

g v e force bewtween particles

Answer 9

g - force directly proportional to product of masses
force inversely proportional to square of the distance between them

e - force directly proportional to product of charges
force inversely proportional to sqaure of the distance between them

Question 10

pd definition

Answer 10

the difference in electric potential between two points in an electric field.

Question 11

what equation can be used to work out the electric field strength in between parallel plates

Answer 11

E = v/d
