We're told that the charge q2 is in static equilibrium.
This means that the net force on q2 due to q and q1 must be equal.
, where k is Coulomb's constant and r is the distance between two charges q1 and q2.
The electrostatic force between q1 and q2:
Charge q2 in the figure is in static equilibrium. Assume q = -8.1 nC.
What is q1 in nC?
