The figure below shows four arrangements of charged particles.
Rank the arrangements according to the magnitude of the netelectrostatic force on the particle with charge +Q,greatest first (use the notation > or = , for example,a=c>b=d).

1st step All steps Answer only
Given information:
The figure shows arrangements of charged particles.
Objective:
Rank the given arrangements.
Explanation:
A charge is the fundamental property of matter that makes it experience the force when it is kept in the EM field.
Consider the arrangements in figures a and d ,
In figure a , both the protons push the charge Q to the left, and in figure d both electrons pull to the right. But since they work together in each figure, the magnitudes of the forces are equal in the figure a and d .
Consider the arrangements in figures b and c ,
But in figures b and c there is one proton and one electron. The forces from these figures on Q act in opposite directions, so the magnitude of the total force will be less than in a or d . Thus, a=d and b=c but b and c are less than a and d .
So the correct arrangement is a=d>b=c . Explanation:
Like charges repel each other and the unlike charges attract each other.
