Question

If charge on object is double then electric field becomes

Answer 1

If charge on object is double then its electric field becomes doubled too

Hope it helped

Answer 2

If the charge on object is double then electric field becomes doubled.

Explanation:

If q is the charge, then the value of electric field at a distance d from the charge is given by :

$E=\dfrac{kq}{r^2}$

If charge on object is doubled, q' = 2 q, new electric field is given by :

$E'=\dfrac{kq'}{r^2}$

$E'=\dfrac{k(2q)}{r^2}$

$E'=2\dfrac{k(q)}{r^2}$

$E'=2\times E$

So, if the charge on object is double then electric field becomes doubled. Hence, this is the required solution.
