What is the Magnitude of Magnetic Force on an Electron in Various Orientations?

AI Thread Summary
The discussion focuses on calculating the magnetic force on an electron moving through a magnetic field at different angles. The relevant formula is F = qvB(sin θ), where q is the charge of the electron, v is its velocity, B is the magnetic field strength, and θ is the angle between the velocity and magnetic field. The charge of the electron is emphasized as a crucial detail for solving the problem. The user expresses initial confusion over the absence of the charge value but acknowledges the need to look it up. Understanding these parameters is essential for accurately determining the magnetic force in various orientations.

Homework Statement


An electron travels at a speed of 2.0x10^4 m/s through a uniform magnetic field whose magnitude is 1.2x10^-3 T. What is the magnitude of the magnetic force on an electron if its velocity and magnetic field:
a. are perpendicular?
b. make an angle of 45 degrees?
c. are parallel?
d. are exactly opposite?

Homework Equations


F = qvB(sin \vartheta

The Attempt at a Solution


I haven't made any attempts because there is no q value...

It is an electron - look up the charge on an electron.
Soon you will have it memorized!

...I'm slightly embarrassed because I completely looked over that detail. Thank you for pointing that out.
 

Thread 'Rolling without slipping on a curved surface'

Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .

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...

Thread 'Trying to understand the logic behind adding vectors with an angle between them'

My initial calculation was to subtract V1 from V2 to show that from the perspective of the second aircraft the first one is -300km/h. So i checked with ChatGPT and it said I cant just subtract them because I have an angle between them. So I dont understand the reasoning of it. Like why should a velocity be dependent on an angle? I was thinking about how it would look like if the planes where parallel to each other, and then how it look like if one is turning away and I dont see it. Since...
