You travel along a path from location A to location B, moving in a direction perpendicular to the direction of the net electric field in that region. What is true of the potential difference VB-VA?(1)VB-VA>0,(2)VB-VA<0,(3)VB-VA=0.

Short Answer

Expert verified

The correct answer is option (3) VB-VA=0.

Step by step solution

01

Concept/Significance of the electric field

When a charge is considered, the space surrounding it is altered in such a way that another charged particle will experience a force owing to the electric field at every point in space.

02

Determination of true of the potential difference

The electric field is perpendicular to this path. So, work done on the charge is given by,

W=I.E=IEcos90°=0

The work done on the charges is zero so the potential difference in the path A to B is also zero.

Thus, the correct answer is option (3) VB-VA=0

The graph in Figure 16.64 is a plot of electric potential versus distance from an object. Which of the following could be the object?

(1) A neutron, (2) A sodium ion (Na+), (3) A chloride ion (Cl−), (4) A proton, (5) An electron

For each of the following statements, say whether it is true or false and explain why it is true or false. Be complete in your explanation, but be brief. Pay particular attention to the distinction between potential V and potential difference ∆V. (a) The electric potential inside a metal in equilibrium is always zero. (b) If there is a constant large positive potential throughout a region, the electric field in that region is large. (c) If you get close enough to a negative point charge, the potential is negative, no matter what other charges are around. (d) Near a point charge, the potential difference between two points a distance L apart is −EL. (e) In a region where the electric field is varying, the potential difference between two points a distance L apart is -(Ef-Ei)L.

An electron starts from rest in a vacuum, in a region of strong field. The electron moves through a potential difference of 44V. (a) What is the kinetic energy of the electron in electron volts (eV)? (b) Which of the following statements would be true if the particle were a proton? Choose both if they are both correct. (1) The kinetic energy of the proton would be negative. (2) The proton would move in the opposite direction from the electron.

You travel along a path from location A to location B, moving in a direction opposite to the direction of the net electric field in that region. What is true of the potential difference VB-VA?(1)VB-VA>0,(2)VB-VA<0,(3)VB-VA=0.

Question: If the kinetic energy of an electron is 4.4×10-18J, what is the speed of the electron? You can use the approximate (non relativistic) equation here.
