Velocity of Electron through potential difference

AI Thread Summary
To determine the velocity of an electron accelerated through a potential difference of 100,000 volts, one can use the relationship between electric potential energy and kinetic energy. The energy gained by the electron is given by the equation VQ, where V is the potential difference and Q is the charge of the electron. This energy converts entirely into kinetic energy, which is expressed by the formula KE = 0.5mv², where m is the mass of the electron. By equating the potential energy to kinetic energy, the velocity can be calculated. Understanding these concepts is crucial for solving problems related to electron acceleration in electric fields.

Using your actual knowledge of the actual charge of an electron and the mass of an electron, determine he velocity of an electron that has been accelerated across a potential difference of 100000 volts.

Please show me how to do this question. Thanks

Hint: when the electron in accelerated over the potential difference, its kinetic energy increases. Is there an equation that relates the electron's energy to voltage?
 
are you able to give me a little bit more infomation about how you find it. I don't really get this topic that well. Thanks

Energy supplied by the pd is VQ=Ve (e is charge on the electron) and all that energy goes into increasing the kinetic energy of the electron (what's the formula for kinetic energy?)
 
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...
