Question

what does q1 and q2 =0 signify in electrostatics

Answer 1

It has no significance since charge can not be zero

Answer 2

Answer:

The value of q1 and q2 equal to 0 will signify that the system will not experience any kind of attraction or repulsion.

Explanation:

According to the question, q1 and q2 equals to zero in electrostatics, signifies the following -  

Given that the charge q1 as well as the other charge q2 is equal to zero. This means the two given charges on the system in totality will account to zero.

q 1 + q2 = 0

This implies that the force acting on the system will also be zero.  

$\begin{aligned} F &=\frac{k q 1 q 2}{r^{2}} \\ F &=0 \end{aligned}$

This further signifies that the system will not experience any kind of attraction or repulsion between the constituents of the system involved.
