Question

Electric Field Treatment (EFT) is a relatively recent innovation in medicine that allows for the electric polarization of patient tissue in a clinical setting. This proceure u useful on a molecular level. For example, EFT can be used to rearrange charges on the ceil membrane, resulting in an induced transmembrane pot inhibit voltage-gated ion channels, which can be useful in treating patients with intracelular sodium deficiency. One resea electroporation. This process involves temporarily permeabilizing the membrane through brief exposure to an electric feld. To begin her study, she sets up two large metai piates separated by a distance D are charged usin charges (either + or -) can then be shot downward through the region at the midway point between the plates. potential. It can also be used to excite is interested in utilizing EFT to deliver drugs through g a battery of voltage V. This creates a region of uniform and constant electric field throughout the region between the plates. Various Blolog/cal/medical pulsed electric feid Figure 1.

Explanation / Answer

1) the negative charges would veer to the right.

The charges move towards the oppositely charged plate.

2) increase the mass of the injected particles.

The electric force is independent of mass. (F = qE)

3) Both the experiments produce same results.

Again, the electric force is independent of speed as well.

4) The particles deflect in such a direction as to decrease their electric potential energy.

Every particle tend to attain stability and lesser the potential energy, more is the stability.

5) Electric force on the charge would double.

F = qE, so doubling q doubles F.
