Homework Statement

Homework Equations



I am not sure. Maybe Archimedes's Principal and f=ma. This could possibly be a control volume problem so also the continuity equation or the momentum equation for control volumes.

The Attempt at a Solution



This is in my first assignment in my aerodynamics class. It was supposed to be a review of Fluid Mechanics 1. All the problems before it for control volume problems, but the statement says it is a hydrostatic problem/rigid body problem. So I'm not sure if we are supposed to use control volume analysis or not. Regardless I'm confused on how to start. I can't think of an equation that would some how give me the angle the water level would make. If anyone could just give me an initial hint or point me in the right direction, that would be awesome.

Thanks!

I thought about it more, and I'm thinking that the surface of the water will be perpendicular to the net force acting on the body. Is that correct?
 

Thread 'Direction of the magnetic field of an oscillating charge'

Hello everyone, I’m considering a point charge q that oscillates harmonically about the origin along the z-axis, e.g. $$z_{q}(t)= A\sin(wt)$$ In a strongly simplified / quasi-instantaneous approximation I ignore retardation and take the electric field at the position ##r=(x,y,z)## simply to be the “Coulomb field at the charge’s instantaneous position”: $$E(r,t)=\frac{q}{4\pi\varepsilon_{0}}\frac{r-r_{q}(t)}{||r-r_{q}(t)||^{3}}$$ with $$r_{q}(t)=(0,0,z_{q}(t))$$ (I’m aware this isn’t...

Thread 'Initial conditions for orbits around a wormhole'

Hi, I had an exam and I completely messed up a problem. Especially one part which was necessary for the rest of the problem. Basically, I have a wormhole metric: $$(ds)^2 = -(dt)^2 + (dr)^2 + (r^2 + b^2)( (d\theta)^2 + sin^2 \theta (d\phi)^2 )$$ Where ##b=1## with an orbit only in the equatorial plane. We also know from the question that the orbit must satisfy this relationship: $$\varepsilon = \frac{1}{2} (\frac{dr}{d\tau})^2 + V_{eff}(r)$$ Ultimately, I was tasked to find the initial...
