Sample Exam 2
Exam 2 Review
JH
Try: +/- or -/+ or ++ or – two charges
on point p!
Try conducting pair!
You can make similar problem using,
two point charges or two sheets of
charges
Maximum happens at the surface (even for
conducting sphere).
In this non-cond. With uniform charge the E
drops like r/R
Other factors can be used. Both inside and
outside values can be generated.
Analogues to gravity,
only vertical
distance matter.
Can you generated x for –ve x-axis side?
If the sizes are different then you make the potential equal (KQ/R). If
identical then make the charges equal
Think off water pockets; when connected the water level is the same
Serial: plates connected without intermediate junction
Parallel: two junction each connecting two plates from the two capacitor
