This is happening on a resistance free surface. There is no friction. Also, you at least need to attempt the problem on your own. Your hint though is to think about force balancing, and that you only need one formula.

Cant post a picture unfortunately. I apologize if its in the wrong forum again, i didnt think Fourier transforms were introductory physics. I ran a search on Fourier and saw mostly advanced physics and calculus and beyond, so i thought this forum was acceptable. The base frequency was...

Homework Statement This is a question from a Physics Lab i recently completed. We used a function generator to provide a signal to a spectrum analyzer that performed a Fourier transform on the signal. In this case the signal was a square wave. When viewing the Fourier transform on a log...

The F equation i used is for a test charge, in CGS units. "c" stands for the speed of light in this case. The B equation is the magnetic field this moving test charge produces. So far as i can understand, u0, the permeability of free space, = (4*pi) / c, if that helps. The books I am...

Great, thanks! So my analysis is correct?

So the magnetic field is the cause of the centripetal force?

Whoops. Actually its F = mv2/r = mrw^2, though r = vw is still correct.

Homework Statement An electron of mass Me, with charge -e, is in a circular orbit in the xy-plane. There is a uniform magnetic field B in the positive z direction. It is moving at constant velocity V. Working in CGS units... Find R in terms of Me, -e, v, and B Find the angular...

Yes i did...thanks again for the check.

The form i am using is just in CGS units...where the SI form is just divided by epsilon*4*pi I believe so that k = 1. As the conductor thickness goes to 0, (d-a) will go to d, and the division by 2 will be negated by the factor of 8 as opposed to 4...so it will go back to the original equation.

Homework Statement An isolated conductor of thickness 'a' is placed between the plates of a parallel plate capacitor. Find the capacitance Homework Equations C = A/(4*pi*d) The Attempt at a Solution C1 = A/(4*pi*((d-a)/2)) C2 = A/(4*pi*((d-a)/2)) 1/C = 1/C1 + 1/C2...

Homework Statement Assume the Milky Way contains about 3 × 10^11 stars that were formed all at once, with an initial mass function: \frac{dN}{dM}\propto M^{-2.35} in the range 0.1–100 solar masses. How many stars in the Galaxy are less massive than the Sun? How much mass do these...

Great, thanks.

Homework Statement A particle of mass M is hanging from one end of a massless spring, while the other is attached to the ceiling of an elevator. The elevator then starts to move upwards at an acceleration equal to g/5. Which way does the equilibrium shift, and what is the magnitude of...

Yes your correct about the original equation...also not sure why they used v for the angular velocity.
