What does `q_(1)+q_(2)= O` signify in electrostatics Or, Two charges `q_(1)`and `q_(2)`,separated by a small distance satisfy the equation `q_(1) +q_(2) = O`. What does it tell about the changes ?

Text Solution

Verified by Experts

The correct Answer is:
The equation signifies that the electric charges are lagebraically additive and here `q_(1)`and `q_(2)` are equal and opposite.
