So for the first question the math is like this
B = m(I/(2pi*r))
B = 4*pi*e-7(15/(2pi*0.1)) = 3e-5
F = qVB*Sin(90)
F = (1.6e-19)(5e6)(3e-5)(1) = 2.4e-17 N
And so if upward is positive, this would point upward?For the second question, the math would be like this?
a)
(1/2)mv^2 = Vq
v = 2.86e5...
For the first question it's these 2 equations right?
B = m(I/(2pi*r))
F = qVB*Sin(90)
I can plug the values in, but I'm missing mu (m). can anyone tell me it?
For the 2nd question, it's the centrepedial force equals the force of the electrons right?
qVB sin(90) = mv^2/r
Magnetic fields (urgent)
Hello, I'm in trouble, I have no idea what to do/look for the formula to solve these 2 questions.
Please help and guide
