AI Thread Summary
To find the final speed of an electron accelerated by a 22kV potential difference, the work done on the electron can be calculated using the formula for work done, which is the product of the potential difference and the charge of the electron. The work done results in a change in kinetic energy for the electron, allowing for the calculation of its final speed. The previously determined work done on the electron is 3.25 x 10^-15 joules. Understanding this relationship between work, potential difference, and kinetic energy is crucial for solving the problem. The discussion emphasizes the importance of applying basic physics principles to determine the electron's final speed.

Homework Statement



Assuming the electron starts from rest, what will be the final speed reached by the electron?

We have p.d. of 22kv, and the 'work done on the electron', worked out previously as 3.25^-15


Homework Equations



*shrug* I swear we have never covered this before

The Attempt at a Solution



No idea how to even begin
 
Physics news on Phys.org
The work done by the p.d.=Change in kinetic energy of the electron

Work done = p.d. x Charge of the electron
 
*facepalm* I should have known that.

Thanks rock.freak!
 

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...

Thread 'Variable mass system : water sprayed into a moving container'

Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...
