Question

Is the force acting between two point electric charges q1 and q2, kept at some
distance apart in air, attractive (or) repulsive when (i) q1q2> 0 and (ii) q1q2< 0?

Answer 1

1) If q1q2 >0, repulsive force operates on them.
    Reason: For q1q2>0, both the charges must be positive. So like charges repel each other.
2)If q1q2<0, attractive force operates on them.
    Reason: For q1q2<0, one of the charges must be negative and other must be positive. So unlike charges attract each other.

Answer 2

Answer:both of them will be repulsive

Explanation:bcoz if q1q2>0 then they both are positive and positive charges repel each other and if q1q2<0 then they both are negative and hence they will repel each other
