Homework Statement


If a proton and an electron are released when they are 8.00×10e-10 m apart (typical atomic distances), find the initial acceleration of each of them.

Homework Equations



F=ma
F=kq1q2/re2
F=kee2/r2

The Attempt at a Solution



Since r=8x10e-10, I solved for the force, because the charge between proton and electron will be the same. From that I got 2.88x10e-10. Then, using F=ma, I divided the force by the mass of the electron (9.10 x 10e-31) and got 3.16x10e11. This was wrong so I am stuck here...

Bump please!
 
The method looks right. I'm not getting the same numbers as you are though. If you get something like e-10 for force and divide by e-31 for electron mass it's nowhere near e11.
 
Sorry, I meant 3.16 x 10e20. Still isn't correct though.
 
Ack! Silly me! My calculator was set up incorrectly! I fixed it!

Thank you for helping me understand that I was doing it correctly though!
 
I was going to suggest you check the calculator batteries, F wasn't right either.
 

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...
