Minimum seperation of two electrons moving toward each other

AI Thread Summary
The discussion focuses on finding the minimum separation between two electrons moving toward each other. Participants are encouraged to use symbols exclusively to derive an algebraic expression for the minimum separation, denoted as ##r##. This approach helps avoid copying and rounding errors, ensuring accuracy in calculations. The thread was initially locked due to confusion between two users but has since been reopened for continued collaboration. The emphasis remains on developing a clear mathematical solution before substituting numerical values.

Homework Statement
Two electrons approach each other moving in opposite directions. When the separation between the electrons is 10 m, the two electrons move with the same speed of 𝑣=38 m/s. What is the minimum distance that the electrons will approach each other before they begin to move away due to the effect of electrical repulsion?

It looks like you have the correct idea. I strongly recommend that you redo the problem using symbols exclusively in order to find an algebraic expression for the minimum separation ##r##. Once you have that, you can substitute numbers at the very end. This eliminates copying and round-off errors and preserves your sanity.

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}...

Thread 'Minimum mass of a block'

Here we know that if block B is going to move up or just be at the verge of moving up ##Mg \sin \theta ## will act downwards and maximum static friction will act downwards ## \mu Mg \cos \theta ## Now what im confused by is how will we know " how quickly" block B reaches its maximum static friction value without any numbers, the suggested solution says that when block A is at its maximum extension, then block B will start to move up but with a certain set of values couldn't block A reach...
