AI Thread Summary
Coulomb's constant, represented as kappa, is defined as 1/(4*pi*epsilon naught), with epsilon naught being 8.85 x 10^-12 F/m. The discussion clarifies that e refers to the elementary charge. Participants confirm that e^2 multiplied by kappa does not equal 1, contradicting the initial assumption. The confusion arises from the values being used, suggesting that the issue may lie in the units or constants applied. The conclusion is that e^2 multiplied by Coulomb's constant does not equal 1.

I'm not really sure how to go about this

whenever I plug in the correct values I don't get 1. Unless I'm supposed to use au.

Well what is Coulomb's constant?

Am I correct in assuming that e is the elementary charge?
 
it's 1/(4*pi*episolon naught) where episolon naught is 8.85 x 10^-12 F/m. yes, e is the elementary charge.

Then there is nothing left to do since as you have now pointed out in your edited opening post, it is clear that

e^2 \cdot\kappa \neq 1
 

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}...
