Given that two spherical conductors of radii r1 and r2 are separated by
x>>(both r), connected by a thin wire, and charged with 7 uC - how is the charge distributed between the spheres (no charge on wire)?
I tried using charge density but:
Qtot/A1+A2 = Q1/A1 + Q/A2 doesn't work by...
Do you mean, the depression cannot be caused by the weight of the mass because there is no external force causing it to weigh anything?
Let me rephrase my initial inquiry: By what means does a mass cause a depression in space-time ? Or is there no direct answer?
The distance between stars is measured by the time it takes light to travel between them correct? How do you measure the time it takes?
for example from CNN "It is 12.7 billion light-years away, meaning the light just recorded -- by NASA's Chandra X-ray Observatory -- took 12.7 billion...
I understand that the curvature is caused by the depression of a mass in the space-time surface. What I don't understand is what is causing this depression. For example, is it the bodie's resistance to the motion of the space-time surface? Or is it that the curvature is caused by the...
The fact that B never fully reaches zero would be a start. Further C/B never fully reaches infinity, since it doesn't have an actual value. Check this out:

What exactly does spacetime curvature mean. I understand that space must be curved, I guess, because of circular motion or gravity?? But how is it that time is curved?
Ok wait, I just realized I made a mistake at the beginning of the thread. I should have clarified that this isn't an indefinite integral. The limits are from (0 to L) so:
1) let u = x+d then x = u-d
(x/x+d)dx = (1-d/u)du = u - dlnu = x+d - dln(x+d)
from (0 to L) = (L+d) - dln(1+L/d)...
