Can someone give me three real life applications of the Millikan Experiment or parallel plates? Also if possible can you give me a little description of how it works.

Also, we are not allowed to use a tv,computer monitor or a printer.

I have no idea what you mean by "real life applications of the Millikan Experiment". I don't know how one "applies" an experiment. The Millikan Oildrop Experiment (I assume that's the one you mean) was done to demonstrate the discreteness of electrical charge and did that very nicely.

As for "parallel plates", I guess you are talking about charged plates. Start off by thinking about capacitors.
 
What I meant in real-life applications is how Millikan's oil drop experiment is used today. Like in what sort of products do we use stuff that Millikan learned. For example a TV uses something simiar to parallel plates to direct electrons.
 
Then I think you misunderstand the point of the experiment. The use of parallel, magnetized or charged plates was well known before that time.

Mass spectrometers?
 
I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...
Thread 'A cylinder connected to a hanging mass'
Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
