Question

What is the nature of force between Q1 and Q2, if Q1.Q2<0?​

Answer 1

Answer:

The electrostatic force is repulsive when q1 q2 > 0, i.e. the two charges have the same signs (either both positive or both negative). The electrostatic force is repulsive when q1 q2 > 0, i.e. the two charges have the same signs (either both positive or both negative).

Explanation:

Answer 2

Answer:

The electrostatic force is repulsive when q1 q2 > 0, i.e. the two charges have the same signs (either both positive or both negative). The electrostatic force is repulsive when q1 q2 > 0, i.e. the two charges have the same signs (either both positive or both negative).
