Question & Answer
Choose the Best Answer
Both forces repel each other.
Both forces attract each other.
The force on the +4 µC charge attracts the +1 µC charge, but the reverse is not true.
There is no force acting between the charges.
Understanding the Answer
Let's break down why this is correct
Coulomb's Law says a positive charge feels a push away from another positive charge. Other options are incorrect because The idea that like charges attract is the opposite of Coulomb's Law; Forces between objects are always mutual; if one pushes back, the other pushes back too.

Definition
Electric field induction occurs in insulators, creating dipoles due to the rearrangement of electrons when subjected to an external electric field. This phenomenon leads to the polarization of insulators, forming layers of induced charges. Understanding electric field induction is essential in studying dielectrics and their impact on electric fields.
