Electric Field from plates?

Question

A particle with a mass of 1.5×10−5 kg and a charge of +2.6 mC is released in a (parallel plate) uniform horizontal electric field of 13 N/C. If the plates are 4.0 cm on each side, how much charge is on each? How far horizontally does the particle travel in 0.40 s? What is the horizontal component of its velocity at that point?

Answer 1

BIG question,bigger answer....so i am skipping calculations....area of plate=16cm2.....you need the distance between the plates (d)to find the capacitance and votage difference...C=εA/d...V=E.d

then Q=charge stored=ie charge on each plate=CV

acceleration=a=Eq/m...E=electric field,q=charge of particle,m=mass

then use s=ut+0.5at^2

s=distance travelled ...put t=0.40sec

V=horizontal component of velocity=u+at..(u=initial velocity=0)...careful about the units..

Answer 2

What did you do to maintain Q consistent? And is the linear length on which A is common plenty extra beneficial than the plate separation? additionally, as rapidly as you have made your set-up, did you constrain the plates in place and safeguard them insulated from each and every distinctive? value floor density and the cost of epsilon are the sole 2 motives which will choose to set the electrical powered powered self-discipline interior the area of an limitless sheet of value. subsequently, you have gotten 2 sheets of opposite value, subsequently the uniform electric powered fields upload as much as a internet uniform electric powered section. in this important undertaking, the stress on the attempt value would not decrease, the area did you get that theory? Coulomb's regulation? Coulomb's law is least confusing ideal for factor fees. the recommendations of the parallel plate capacitor have been derived from limitless calculus in accordance with Coulomb's law, besides the shown actuality that could now not the equivalent ensuing kit. as quickly as you have have been given a uniform sheet of value, the sector lines do now not unfold out as you progression far flung from the sheet of value, subsequently, the cost of the undertaking keeps to be safeguard, and subsequently thepersistent on that particle keeps to be safeguard. think of of decrease back on the topic of the stress lowering, it may proceed to be consistent.

Answer 3

Seems like you are missing some info. Released?? Im not sure of the physical interpretation of this. Maybe a diagram?
