Telescope in Milikan Experiment

AI Thread Summary
The discussion centers on the use of a telescope in the context of Milikan's oil drop experiment, with a participant questioning its purpose. There is confusion regarding whether a telescope or a microscope is more appropriate for measuring the velocities of electrons in the experiment. One contributor points out that the Wikipedia entry refers to the instrument as a microscope, which aligns with the small scale of the oil drops being observed. The conversation highlights the importance of clarity in terminology when discussing scientific experiments. Ultimately, the distinction between a telescope and a microscope is crucial for understanding the experimental setup.

My book mentions a telescope in order to measure velocities of electron.But does not explain why to use it?Plz. tell me why to use a Telescope?Thanks.

The Attempt at a Solution

 
Physics news on Phys.org
Could they mean microscope? AFAIK, Milikan's oil drop experiment was conducted in a small container, and small motions of the oil drops were being observed...

The drawing at the wikipedia.org entry for this experiment definitely calls it a "microscope":

Thread 'Errors and significant figures'

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'

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...
