Magnetic field in 3 dimensions

AI Thread Summary
The discussion revolves around calculating the net magnetic force acting on a charged particle in a magnetic field with components along the x and y axes. The magnetic field has a magnitude of 0.0431 T in the +x direction and 0.0686 T in the -y direction, while the particle has a charge of +1.70 × 10-5 C and moves along the +z axis at 4.24 × 10^3 m/s. Participants suggest using the Pythagorean theorem to find the net magnetic field strength (Bnet). The equation F = qvBsinθ is referenced for calculating the force, and the angle with respect to the +x axis is also to be determined. The conversation emphasizes the importance of correctly calculating Bnet to proceed with the force calculations.

Homework Statement


One component of a magnetic field has a magnitude of 0.0431 T and points along the +x axis, while the other component has a magnitude of 0.0686 T and points along the -y axis. A particle carrying a charge of +1.70 × 10-5 C is moving along the +z axis at a speed of 4.24 × 103 m/s. (a) Find the magnitude of the net magnetic force that acts on the particle. (b)Determine the angle that the net force makes with respect to the +x axis.

F= qvBsinθ

The Attempt at a Solution


I don't know how to get Bnet, I was thinking it would be by using the pythagorean theorem.

Thread 'Struggling to make relation between elastic force and height'
Hello guys this is what I tried so far. I used the UTS to calculate the force it needs when the rope tears. My idea was to make a relationship/ function that would give me the force depending on height. Yeah i couldnt find a way to solve it. I also thought about how I could use hooks law (how it was given to me in my script) with the thought of instead of having two part of a rope id have one singular rope from the middle to the top where I could find the difference in height. But the...
Thread 'Voltmeter readings for this circuit with switches'
TL;DR Summary: I would like to know the voltmeter readings on the two resistors separately in the picture in the following cases , When one of the keys is closed When both of them are opened (Knowing that the battery has negligible internal resistance) My thoughts for the first case , one of them must be 12 volt while the other is 0 The second case we'll I think both voltmeter readings should be 12 volt since they are both parallel to the battery and they involve the key within what the...
