b)Lines are close together where the field is strong.
c)The direction of electric force on a charge is tangent to the field line
d) All these statements are true.
e) None of are true.
.
3. If the negative charge is moving to the north in an electric field which is directed to the north, the charge will:
a) speed up
b) slow down
c) be unaffected
.
answer with short reason why is the answer plz :)

Explanation / Answer

1)

When a point charge is placed in a electric field it experiences a electric force F = q*E

F/q = E

So the answer is C) Electric field acting on the test charge

---------------------------------------------

2) the direction of electric field is tangent and not the force to the field line

So C) is the correct option

3) electric filed is always from positive to negative

So the elctron and filed are in same direction means electron is moving towards the negative end of the field,results repulsion.hence charge will skow down

So the correct answer is b) slow down
