Consider two positively charged particles, one of charge q0 (particle 0) fixed at the origin, and another of charge q1 (particle 1) fixed on the y-axis at (0,d1,0). What is the net force F⃗ on particle 0 due to particle 1? Express your answer (a vector) using any or all of k, q0, q1, d1, i^, j^, and k^.

Answer:

[tex]F_{10} = - \frac{k_{q1}* qo }{d_{1} ^{2} } j[/tex]

Explanation:

The net force ( F ) on particle 0 due to particle 1  can be expressed as

[tex]F_{10} = \frac{K_{q1}*qo }{r_{10} ^{3} } r_{10}[/tex]

k = coulomb constant

[tex]r_{10}[/tex] = distance between charge o and charge 1

to get the vector form ( attached below ) we substitute [tex]d_{1}[/tex] for [tex]r_{10}[/tex] and [tex]- d_{1} j[/tex] for [tex]r_{10}[/tex]

The net force on [tex]q_{0}[/tex]  by [tex]q_{1}[/tex] is , [tex]F=-K\frac{q_{0}*q_{1}}{r^{2} }j[/tex]

The force between two charges is given by Coulomb force law.

                 [tex]F=K\frac{q_{0}*q_{1}}{r^{2} }[/tex]

Where K is Coulomb constant, [tex]K=9*10^{9}Nm^{2}/C^{2}[/tex]

and r is the distance between both charges.

Here given that, [tex]q_{0}[/tex] is located as (0, 0, 0) and [tex]q_{1}[/tex] is located at [tex](0,d_{1}, 0)[/tex]

The force on [tex]q_{0}[/tex]  by [tex]q_{1}[/tex] in the negative y - axis.

So that , Direction of force is,  [tex]-j[/tex]

Hence, the net force on [tex]q_{0}[/tex]  by [tex]q_{1}[/tex] is , [tex]F=-K\frac{q_{0}*q_{1}}{r^{2} }j[/tex]
