Some examples from this set of practice questions
1.
What is an \'Equipotential Surface\'?
Answer: A closed surface where the electric potential is constant
2.
Define \'Isolated Charge\'.
Answer: A charge where the force acts equally in all directions and on a spherical surface area
3.
Describe the relationship between \'Potential Energy\' and work in a capacitor.
Answer: Potential energy is the work done to charge a capacitor, stored as 1/2 CV2
4.
Explain the behaviour of Electric Field inside a conducting sphere.
Answer: The electric field is zero inside a conducting sphere
5.
What is meant by \'Superposition\' in the context of charges?
Answer: It is the vector sum of forces from multiple charges
6.
How is the magnitude of the force in Coulomb\'s Law related to the distance between charges?
Answer: The magnitude of the force is inversely proportional to the square of the distance
7.
Explain what an equipotential surface is in electrostatics.

What is the superposition principle in electrostatics?
Answer: It is the vector sum of forces from multiple charges
9.
Explain the relationship between the force in Coulomb\'s Law and the magnitudes of the charges.
Answer: The magnitude of the force is proportional to the product of the magnitudes of the charges
