Question
Which of these quantities is a function of position in space, not a function of the charge at the point in space?
A) Electric potential
B) Electric force
C) Electric charge
D) Electric potential energy
In which case have we increased the potential energy U of the system?
A) Separating two - charges
B) Separating a + and - charge
C) Separating two + charges
How do the voltages of standard batteries compare to the voltages in a typical static electric "shock"?
A) These two situations can't be compared
B) Batteries have about the same voltage
C) Batteries have much less voltage
D) Batteries have much more voltage
Explanation / Answer
(1)electric force. so option B is correct
(2) (B) potental energy at some configuration would be k q1 * q2 / r . So If two positive charges or negative charges are moved away then potential energy decreases. So answer is B. In this case due to negative sign on one charge and + on another, potential energy of system increases
(3)(A)Batteries have much less voltage.
