(a)
The net force on the middle particle.
(a)
Answer to Problem 40A
Explanation of Solution
Given:
The charge on the left particle is
The charge on the middle particle is
The charge on the right particle is
The middle charge is equally spaced from right and left charges by
Formula used:
Coulomb’s law: If
Where
Calculation:
The electrostatic force between the middle and left charge is
Electrostatic force between the middle and right charge is,
Let left be the negative direction. Hence the net force on the middle charge can be calculated by,
Substituting the numerical values in equation
Conclusion:
Therefore, the net force on the middle particle is
(b)
The net force on the right particle.
