comment Optimal slit width in Young's double slit experiment
I have seen it. Coincidentally, that video is what inspired me to do the experiment myself. Unfortunately he uses manufactured slits(I can see they are pretty close together and thin).

comment Gravitational force exerted by a rod on a point mass
You are right. One cannot integrate $x$ wit respect to $dx$. Maybe you are misinterpreting the author. A link to that solution would help.

comment Two boxes that are connected pushed by force - what happens between two boxes?
PS why they move with the same acceleration is not because the forces cancel out, but because the glued bonds would break if they didn't. They are constrained by the glue to move with the same acceleration.

comment Two boxes that are connected pushed by force - what happens between two boxes?
Because according to newton's law, the forces are exactly equal in magnitude and exactly opposite in direction which is why they cancel out.

comment Two boxes that are connected pushed by force - what happens between two boxes?
Do you mean to ask why an internal force(like the force between those two boxes) has no net effect on whole system of those two boxes?

Then the equation you get is correct, except that you will also subtract $1$, the distance travelled by B

comment Direct collision on smooth surface
shouldn't it be $(\frac{1}{u(1+e)})(u(1-e))$?
