Per forum rules, you must show some attempt.balikci said:
You have quoted a relevant equation. Start by explaining what the variables in it mean (so we can correct any misunderstanding) then what numbers from the problem should be plugged in where.

I am new. I am sorry. I am puting parts which I solved here. I couldn't go further from here.

You started well with the expression for F1 and F2, but there seem to be subscripts I can't read on the charges 6 and 3. What are these?balikci said:
Then you resolved into x and y components, but you are not asked to do that for the first part. Just evaluate the expression you have.
You have not attempted the second part, right?

For the first part everything looks pretty good.
Your choice of x and y labels is a bit unconventional, but there is nothing wrong with that. The one thing that I can’t figure out is your scientific notation as a subscript. I’ve never seen that before. It is particularly alarming as those all appear to be 4 s instead of 6s. Anyhow, you get the right power in the end, so it must make sense to you. You might want to consider doing something more conventional so it’s easier for the grader to understand and give you credit. Nevertheless it all appears correct and you just need to finish.
Now, what about part B?
