Charges
The amount of charge on a(n) proton/electron
What is 1.60x10-19 C
how does electric potential differ from electric potential energy?
what is Electric potential is the voltage per unit charge whereas electric potential energy is energy measured in joules?
Electric Potential
What is a Volt (joule/coulomb)?
Potential Energy isn't real
What is FALSE?
Hamblen's office hours
What is Tuesday, Thursday, and Friday from 11-12pm
Process of charging an object by bringing a charged object close to another object that is grounded
what is charging by induction?
If a negative charge is moving AWAY from another positive charge, what happens to its change in electric potential energy (EPE)?
what is it increases
Electric Field
What is newton per coulomb?
A positive charge accelerates from a region of higher electric potential towards a region of lower electric potential
what is TRUE?
When are SI sessions?
what is Wednesdays 2:30-3:30 and Fridays 11:20-12:30pm?
the electric force between two charges is strongest when?
What is when the charges are close together?
Suppose that the electric potential outside a cell is higher than that inside the cell by 0.083 V. How much work is done by the electric force when a Potassium ion (charge=+e) moves from the outside to the inside? (3 sig figs)
what is 1.33x10-20J
Power
what is watts?
the net electric force does work as a charge moves on a equipotential surface
What is false?
Equipotential surface is a surface on which the electric potential is the same everywhere
When is chapter 19 homework/extra credit due?
What is Next Wednesday at 11:59pm?
If two charged objects have a repulsive force of 0.080 N and if the distance separating the objects is halved, then what is the new force?
0.032
(The electrostatic force is inversely related to the square of the separation distance. So if d is two times smaller, then F is four times larger. Four times 0.080 N is 0.320 N)
If two or more charges are present, the potential due to all the charges is obtained by....
what is adding the individual potentials together?
proportionality constant "k" in coulombs law
what is (N*m2)/(C2)?
(Newtons times meters squared per Coulombs squared)
Electric potential is a vector quantity
What is false?
When is your first exam?
What is September 29?
At what separation will two charges, each of magnitude 6.0x10-6C, exert a force of 6.1N on each other?
What is 0.23m?
when moving closer to any negative charge, what happens to the electric potential?
The Permittivity of Free Space
What is C2/ N*m2 (Coulombs squared per Newton times meters squared) ?
The Feld lines around a charge (-q) are directed radially inward
what is true?
