Chap 22 Elec Fields Flashcards
Don’t be stupid,
What is the force at any point in a uniform field no matter where
Not only is E constsnt but the FIRCE IS CINSTANT DOESNT CHANGE
Don’t be afraid to use SIMULATANOUS equations to find out potentials etc
Or just formulate equations with unknowns
Because they will prolly cancel later
If you have ti find unknown at a point, what value for distance should you prolly go for
Just ALWAYS TRY FIND BASED ON DISTANCE ITS ASKIGN , LESS CHANCE OF MISTAKE
Remember if charged were psotive negative before and then they both became positbe, why had the FORCE CHANGED DIRECTION
work out the force before and after
Remember a negative sign means attraction and positive is repulsion
Remember if they both psotive it’d gonna repel
And if force is now negative it’s gonna be other way from before
When you have a plate of charge, how must all the electric field lines enter (what way)
If the field lines aren’t uniform how will they snd must be
Must all enter it PERPENDICUALRLY
2) msjt be curved some how
