Match the following laws with their correct descriptions. : Ampère's law. Gauss's law in electrostatics. Coulomb's law Gauss's law for magnetism. Biot-Savart law. 1. The net flux through any closed surface is always zero. 2. The electric force exerted by one charge on a second charge is related to the magnitude of the charges and their separation. 3. The line integral of B⇀⋅ds⇀ around any closed path is equal to the product of the total current passing through a surface within the path and the permeability of free space. 4. The net flux through any closed surface is equal to the enclosed charge divided by the permittivity of free space. 5. The magnetic field at some point in space is related to both the current in and the distance from the wire element that induces the field.

concern recent clinical results using electric fields to disrupt rapidly dividing tumor cells. When cells are dividing, some elements of the cell develop a small net charge, and others develop a dipole structure with a positive charge on one end and a negative charge on the other. When a uniform electric field is applied to the body, the field will not be uniform inside the body. The motion of charges and polarization effects, both of which vary strongly from place to place, create a field that is quite variable at the level of the cell. The field is strong in some places and weak in others. The varying field exerts forces and torques on the cell components. This can disrupt cell division, which can have an especially large impact on the rapidly dividing cells in a tumor. To illustrate this idea, we consider a cylindrical element with a dipole structure but no net charge,embedded in a dividing cell. The varying environment of the cell createsa local variation in the strength of the…
