1.
The electric field strength is equal to
the potential
the gradient of the field
minus the potential gradient
the area under the V–r graph
2.
The potential changes by 60 V over 0.30 m in a uniform field. E is
18 V m−1
2.0 V m−1
0.005 V m−1
200 V m−1
3.
A graph of V against distance for a uniform field is
a hyperbola
a straight line
a parabola
a horizontal line
4.
The area under an E–r graph between two points represents
the force
the charge
the potential difference
the energy
5.
The V–r graph of a point charge becomes flatter far from the charge, which means the field
decreases
increases
is constant
is zero everywhere
6.
Equal-spaced parallel plates 5.0 mm apart carry 100 V. Halfway between them the potential is
0 V
50 V
100 V
25 V
