Two charges \( Q \) and \( 4Q \) are separated by a distance of 6 cm. The distance of the point from \( 4Q \) at which the net electric field is zero is:
Two charges \( Q \) and \( 4Q \) are separated by a distance of 6 cm. The distance of the point from \( 4Q \) at which the net electric field is zero is:
Show Hint
To find the point where the electric field is zero, use Coulomb's law and equate the electric fields from both charges at that point.

The Correct Option is D
Solution and Explanation
For the electric field to be zero, the electric fields from both charges must cancel each other out. By applying Coulomb's law and solving for the point where the fields cancel, we find that the distance is 4 cm.
Thus, the correct answer is option (4).
