Sorry for replying late.. yes after a bit of thinking I've figured it out, like you said, since the apparatus is moving we are seeing it as if it moves along an angle. :)

Hello, I am newly learning special relativity. I have this particular doubt> Why is light moving along the hypoteneuse of the triangle while we are moving the apparatus? (Its not like it has a horizontal component of velocity which is equal to the velocity of the apparatus).

Heres the working... sorry, i can't find my mobile phone data cable.. had to do it in paint... http://hostmypicture.com/images/untitlete.png

i am calculating the net electring field... i guess the two kq/0's cancel out one being negative, but its just not coming. i mean bot hare coming out to be positive...

Homework Statement Charges +q and -q at points A and B respectively separated by distance R. Required to calculate the potential difference between these 2 points. Homework Equations I want to do in two ways.. i.e once by integrating the electric field and the other by directly finding the...

I too was speculating about the contact point being the ground and not the point of the sphere touching the ground... and on imagining the fact that even if the sphere rolls a bit forward, the torque due to friction remains zero since the line of force intersects the point...so yeah, makes...

One more serious doubt... In feynman's tips on physics' problems... there is one regarding marble rolling... "An amusing trick is to press a finger down on the marble, on a horizontal table, in such a way that he marble is projected along the table with initial linear speed v0 (v-naught) and...

oooh, i get it... yea! thank you very much.

So there are two concentric conducting spherical shells one with radius R and another 2R with charge +Q and +2Q respectively... Now the two are connected by a conducting wire. Why does the entire charge flow to the outer shell? Please clarify my doubts. I will be grateful.
