4- When a (h) charge freely moves in an electric field E: it will always move from a higher potential to a lower potential , (T/F)? If the charge is negative it will always move from the higher potential to the lower one (T/F)? 5-In an electric field pointing from West to East: a) A proton will move from b) An electron will move from to to 6- When a (+) sodium ion traverses the axon membrane from the negative...
BULJLIUI J PUHILJ) Given an electric field that points upward. When a negative charge moves upward in this field the field does zero work on it and the potential energy does not change. the field does negative work on it and the potential energy increases. the field does positive work on it and the potential energy increases. the field does positive work on it and the potential energy decreases. the field does negative work on it and the potential energy...

If a negative charge is placed in an electric field, will t move toward a region of higher potential or lower potential? What will happen to its electric potential energy? What will happen to its kinetic energy? What will happen to its velocity? For a particles with charge Q, what is the formula for the Electric Potential, V, and the formula for the Electric Field, E? Electrons in a TV tube are accelerated from rest by a potential difference of...
Chapter 17 Homework 1. If a negative charge is initially at rest in an electric field, will it move toward a region of higher potential or lower potential? What about a positive charge? How does the potential energy of the charge change in each instance? Explain.
A +50µC charge moves along a straight line a distance of 20 cm in a uniform electric field of 120 N/C. The proton is traveling at an angle of 30 degrees relative to the direction of the electric field. How much electrical energy (in Joules) did the charge gain or lose? And is it a gain or loss? When is it easier to calculate the energy in eV and then convert to Joules if necessary? When is it easier to...
