1) How could we determine if the electric potential measurements over the surface of the conduction sheet give an accurate picture of the electric field across the sheet? How would you test the accuracy?
2) Describe a way of specifying the precision of the electric field map. How would you change the experiment to improve the precision of the map?
3) What would it mean to say that an electric field map is accurate but not precise? Could it be precise but not accurate

1- For a uniform electric field, how is the electric potential energy similar to the gravitational potential energy in a uniform gravitational? 2-If a positive charge and a negative charge moving the same way in an electric field have the same change in electric potential energy? 3-For a positive charge moving in an electric field, which direction of motion will cause the electric potential energy to increase? Decrease? Stay constant? 4-How would the answers to the previous question be different...

Electric Potential 9-2 1) Picture a conducting sphere with a net positive charge on its surface. Discuss the followin estions with your lab partners. a) Why must all of the excess charge on the conductor reside on the surface of the sphere? b) We know that at equilibrium the electric field inside the conductor must be zero. Does this mean that the electric potential inside the sphere is zero? c) Is the potential changing inside the conducting sphere? d) How...

1) How do you determine the direction of the electric field from afield map? a The electric field is perpendicular to the field lines everywhere. b The field lines point in the direction of the electric field. c The field lines point in the opposite direction of the electric field. d You can not determine the direction of the electric field by the field map alone; the sign of the charge is needed 2) An arbitrarily shaped uncharged conductor is...

3.1 Pre-lab In the lab on electric potential and electric field lines, you noted that charged par- ticles produce electric fields and these electric fields, in turn, act on charged par- ticles. However, you then proceeded to produce an electric field geometry using conductors held at a particular electric potential. What happened to the electric charges? Electric charge and electric potential are closely related to each other. Putting charge on a conductor raises its electric potential. It is usually much...
