A particle with charge q is placed at a corner of a cube with side length a. Determine the net electric flux through the cube. (Use any variable or symbol stated above along with the following as necessary: ε0

Φ = Q/ε0 = q/ε0

Explanation:

The electric flux through any Gaussian surface is equal to the net charge inside the surface over the dielectric permitivity of vacuum. This is the Gauss theorem for electric flux trough a surface. In this case is not important that the suface is a surface of a cube.

I hope this is usefull for you!

explanation:

considering the bohr theory, the type of connection that requires the transfer the answer conuldn't be right

the answer is the first electromagnet (a). this is because it has more coils around the ferromagnetic material. increasing the number of coils increases the surface area in which the metal interacts with the current in the coil. this enables more atoms in the metal to become aligned hence becoming more magnetized.
