Question 1.
What is surface charge density?
Show hintHide hint
Think about how charge is spread over a surface.
Question 2.
What are the units of linear charge density?
Show hintHide hint
What does 'linear' refer to?
3Question 3.
What is surface charge density?
- Charge per unit area
- Charge per unit volume
- Charge per unit length
Show hintHide hint
Consider what 'surface' refers to.
4Question 4.
True or False: Linear charge density is measured in C/m.
- True
- False
Show hintHide hint
Remember the units assigned to linear measurements.
Question 5.
A flat conductive sheet has a uniform surface charge density of 8 μC/m². Calculate the electric field just above the sheet.
Show hintHide hint
Use the formula for an infinite charged plane and remember to consider it for the field's direction.
Question 6.
Consider a charged ring of radius R carrying uniform charge Q. Find the electric field at a point along the axis of the ring at distance z from the center.
Show hintHide hint
Break the electric field contribution into components along the axis and integrate.
