Yeah, I too don't understand how the charge is distributed. Vela, I get your point, but I could not get what kind of charge distribution the solution refers to. The solution (which was very brief and without details) just mentioned the line which I mentioned above : "when the two wires form a...

Well this isn't exactly 'homework', this problem is taken from a physics competition. ^^ Actually, the solution to this problem says that " when the two wires form a capacitor charges reside only on the inner side;' Then Gauss Law has been used to calculate the field and then the electric...

Homework Statement Consider two long parallel and oppositely charged thick wires of radius d with their central axes separate by a distance D apart. Obtain an expression for the capacitance per unit length of this pair of wires Homework Equations \oint \vec{E}\cdot d\vec{a}...

Thank you tiny-tim. I should've noticed that myself. :)

Homework Statement A small sphere A of radius r and mass m rolls without slipping inside a large hemispherical bowl of radius R. The sphere A starts from rest at the top point on the rim of the hemisphere. Find the normal force exerted by small sphere when it touches the bottom of the...

yes it is
