1.
Electric potential at a point is defined as the work per unit positive charge in
bringing a test charge from infinity to the point
moving a charge around a circuit
holding a charge at the point
moving a charge between two plates
2.
The potential at 0.60 m from a charge of +2.0 nC is
300 V
30 V
3.0 V
10 V
3.
The potential at the midpoint between +Q and −Q is
kQ/r
2kQ/r
zero
−kQ/r
4.
A positive charge is moved from 0.20 m to 0.10 m from a positive point charge. Its potential energy
decreases
stays the same
becomes negative
increases
5.
The work done moving 3.0 µC through a potential difference of 200 V is
6.0 × 10−8 J
6.0 × 10−4 J
6.7 × 107 J
0.067 J
6.
As the distance from a positive point charge doubles, the potential
quarters
doubles
halves
becomes zero
