What is the magnitude of the force on the plus plus 4Q charge?

Answer 1

To determine the magnitude of the force on a charge of (4Q), we need to know the arrangement of other charges and their distances from the (4Q) charge. The force can be calculated using Coulomb's law, which states that the force (F) between two point charges is given by (F = k \frac{|q_1 q_2|}{r^2}), where (k) is Coulomb's constant, (q_1) and (q_2) are the magnitudes of the charges, and (r) is the distance between them. Without specific values for the surrounding charges and their distances, we cannot provide a numerical answer.
