Hi I am a beginner in this topic. I didn't understand this question type clearly.What does it mean" With Magnitude and Unit Vectors" exactly? May you help me for the solution step by step :). Thanks in advance.

Yes I learned the vectors,coordinate system but I don't know how can I use them on this question.Welcome to the PF.
Your thread has been moved to the Schoolwork forums.
We cannot do your schoolwork/homework for you, but perhaps we can give you a few tips to help your understanding so that you can start working on the problem.
What have you done with vectors so far? You know that vectors have a magnitude and direction, right? And have you learned about coordinate systems like Caretesian coordinates, where there are x and y directions, etc.?
So start by drawing an x-y set of axes on the diagram. I would probably make the (0,0) point at the A charge, with the x-axis to the right and the y-axis pointing up.Yes I learned the vectors,coordinate system but I don't know how can I use them on this question.
Do you know charged spheres will apply force on each other?Yes I learned the vectors,coordinate system but I don't know how can I use them on this question.
Yes I knowDo you know charged spheres will apply force on each other?
What’s the expression for that force? I mean is there any law which governs how two charged spheres will apply force on each other ?Yes I know
I think you mean Coulmb's LawWhat’s the expression for that force? I mean is there any law which governs how two charged spheres will apply force on each other ?
Yes. Can you please write out the Coulombs Law?I think you mean Coulmb's Law
F=(k*(q1*q2))/r^2.Yes. Can you please write out the Coulombs Law?
But force is a vector quantity, the expression which you have given doesn’t involve the direction of the force. Can you fix it? Can you do something so that we get a vector quantity in that expression of Coulombs Law?F=(k*(q1*q2))/r^2.
Sorry I don't. How can I do that?But force is a vector quantity, the expression which you have given doesn’t involve the direction of the force. Can you fix it? Can you do something so that we get a vector quantity in that expression of Coulombs Law?
$$\vec{F} = k \frac{q_1 ~q_2 }{r^2}~ \hat{r}$$ the force acts on the line joining the two charges.Sorry I don't. How can I do that?
Thanks I have an idea now. :)$$\vec{F} = k \frac{q_1 ~q_2 }{r^2}~ \hat{r}$$ the force acts on the line joining the two charges.
