Answer:
b)1 :3
Explanation:
Lets that
The value of a positive charge = q
As we know that electric filed on a point charge given as
[tex]E=\dfrac{Kq}{r^2}[/tex]
Where ,K=Constant
q=Charge ,r=Distance
If the value of the charge gets tripled ,q'= 3 q
Then electric filed E'
[tex]E'=\dfrac{Kq'}{r^2}[/tex]
[tex]E'=\dfrac{3Kq}{r^2}[/tex]
E' = 3 E
Therefore we can say that
[tex]\dfrac{E}{E'}==\dfrac{1}{3}[/tex]
therefore the answer will be --
b)1 :3
