1. voltage is a measure potential energy per unit charge. if youwere a charge and moved from a higher voltage to a lower voltagehow would your kinetic energy change?
2. what would the firection of the electrical force acting on yoube?
3. how does your answer change is you are a negative charge?
4. what is the firection of the electric field in each case (isthere any differences)?

Problem1.

A) Asmall negative charge is released from rest inan electric field.Will the charge move toward a region of

higher orlower potential energy? Will the chargemove toward a region ofhigher or lower voltage?

B) Inwhat direction, relative to the direction ofan electric field, isthe voltage constant?

C) Whatis the voltage difference between two places insideaconductor?

What is the answer to this question? The one given seems wrong orincomplete.

If an electric field is defined as the force per unit charge thatwould act on a positive test charge q placed at that point thenwouldn't the electric field from the metal sphere before thepositive test charge be equal to the electric field experiencedwhen the positive test charge is placed near the sphere?
