Title: Physics help please!!!
Post by: madikay on June 03, 2009, 10:25:33 am
Can someone please help me on this experiment?
-describe an experiment to show the corresponding force on beams of charged particles.
thank you.

Pass them between 2 oppositel charged plates and measure the deflection s . This will be equal to 1/2at^2 where a is the acceleration produced by the electric field=Eq/m and t=d/v the time between the plates so s=1/2Eq/m*(d/v)^2

Ok shushuIG let me break it down for you.
Pass the them through oppositely charged plates.
One must be positively charged the other negatively charged.
The positively charged particles are attracted to the negative plate and the negative to positive at right angle to the direction of force, this shows corresponding force on beams of charged particles.
Am i right Astar?
