Solution

The correct option is D E3
Let the distance between two point charges q and 3q is r.

Now electric field due to 3q at the location of qis given by,

E=k(3q)r2=(3)kqr2 .....(1)

Again, electric field due to q at the location of 3q is given by , E=kqr2 ......(2)

from equations (1) and (2), it is clear that

E=3E

so, E=E3 ,

hence, electric field due to q at the location of 3q is E3
