Question 1.
What is potential energy in the context of charged systems?
Show hintHide hint
Think about what happens to energy when charges are moved closer.
Question 2.
Define path independence in electrostatics.
Show hintHide hint
Reflect on conservative forces.
3Question 3.
What is the work done to move a charge from point R to point P in a conservative field?
- Depends on the path taken
- Equals the potential energy difference
- Zero work is done
Show hintHide hint
Reflect on the characteristics of conservative forces.
4Question 4.
True or False: The absolute value of potential energy matters.
- True
- False
Show hintHide hint
Consider what is physically meaningful in energy calculations.
Question 5.
Three point charges are located at the vertices of an equilateral triangle of side length 1 m, with charges of +3uC, -3uC, and +5uC. Calculate the total potential energy of the system.
Show hintHide hint
Use geometry to find distances and apply the potentials accordingly.
Question 6.
Derive an expression for the potential energy of a uniformly charged sphere of radius R and total charge Q.
Show hintHide hint
Consider the symmetry and how to represent the contributions mathematically.
