(adsbygoogle = window.adsbygoogle || []).push({}); [SOLVED] Tension in a string of a object being pulled by a magnet

1. The problem statement, all variables and given/known data

An Iron bolt has a mass of 65.0g and hangs from a string 35.7cm ong. Top end of string is fixed. Without touching it, a magnet attracts the bolt so that it remains stationary displaced horizontally 28.0cm to the right from previously vertical line of string.

a) draw free body diagram of bolt.

b) find tension in string

c.) find magnetic force on bolt.

2. Relevant equations

F= ma

[tex]\sum F= 0[/tex]

3. The attempt at a solution

a.)

I tried drawing the free body diagram and also in my opinion how the object would be in a drawing..

I'm not sure what to do now since my text isn't clear on what I do to find tension and only has 1 example.

Also I'm not sure about the magnet force pulling on the bolt but I assume it would be a F ...

I do know that the sum of forces = 0 since it since it isn't moving...

but after that I'm not sure what to do...

~I assume I find the angle that it goes out to the horizontal and then use that to find the x and y components of the tension??

But I'm not sure how to resolve that either...

so basically I'm stuck past a.)

Thanks
