-
Some equations, some vectors and some calculations.
-
Combination of fields from a bundle of wires.
-
Practice at superimposing magnetic fields.
-
Field and force (no prior knowledge required for the force)
-
Evaluation of the vector superposition of fields arising from four point-charges. This is a problem of vector addition, vector magnitudes and scalar (dot) products with a bit of trigonometry thrown in for good measure.
-
Recollection of formulae, combining and re-arranging equations, and evaluating quantities, all while keeping appropriate units in place.
-
Mathematical relationships and their evaluation for parallel plate capacitors.
-
Questions relating to the principles of application of Gauss' Law to simple systems.
-
Determining a charge from the work done in moving an electron between two points in the field of the point charge.
-
The electrostatic potential due to a point charge is calculated at three points, who of which are at the same distance but different directions. This relates to the idea that the equipoptentials of a point charge are spheres centred on the charge, so all points at the same distance are at the same potential.
This question requires unit conversion, numerical calculations and some critical evaluation.

Simple numerical evaluation using a given formula.
-
Evaluation of conceptual understanding and precise inclusion of direction when combining vectors.
-
Concepts and calculation involved in the use of Coulomb's Law for both the field and the force, including units and directions, and then a comparison with a point-dipole approximation.
