a straight wire that is 0.60m long and carrying a current of 2.0a is placed at an angle with respect to a magnetic field of strenght 0.30t if the wire experiences a force of magnitude 0.18 n what angle does the wire

The  angle is  

Explanation:

From the question we are told that

    The length of the wire is  

    The current is  

    The magnetic field strength is  

     The magnitude of the magnetic force is  

Generally the magnetic force exerted on the wire is mathematically represented as

Making the subject

substituting values    

the box does not move because you need to use a force greater than 300 n. you are only using 50 n. it needs to at least be 301 n for the box to move because then it is an unbalanced force and it will move the way that the greater force is pushing it. if you use only 300 n it will be a balanced force and will not move because the force you are exerting on the   box is the same as its force.

hope this !

im sorry if i went too in depth, i am going to include a link to a video on khan academy that will explain this.   hope that you like the video and that it explains more in detail to you.

that is the link.

cancer risk hope this
