Charge Electrons

AI Thread Summary

To determine the number of electrons on a sphere charged with -1 x 10^-5 C, the correct method involves dividing the total charge of the sphere by the charge of a single electron, which is -1.6 x 10^-19 C. The calculation should yield approximately 6.25 x 10^13 electrons. A misunderstanding may arise from the sign of the charges, but the method of division is correct. If the computer indicates an error, it could be due to input format or rounding issues. Accurate calculations confirm that the sphere contains around 6.25 x 10^13 electrons.

I have a question that i can't figure out, if a sphere is charged with electrons to -1 x 10^-5 C. The charge of an electron is -1.6 x 10^-19 C. How many electrons are there on the sphere?

I simply divided the electron charge by the charge of the sphere but it says I'm wrong. Is the problem me or the computer?

That's how you're supposed to do it. You should get something like 6 times 10^13.

Thread 'I've come across another fluid pressure problem I don't understand'

Neglect gravity other than that of water; neglect friction. F1=ρgsh=1000*10*1*(1+4)=50000 N; F1=ρgsh=1000*10*0.1*4=4000 N; F3=50000-4000=46000 N?

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 'Understanding Forces and their Vector Components'

I was told forces are vectors so they can be divided into x and y components, but what about the normal force or the force of static friction? do you divide those into x and y components if say you had a block that was lying on an angled surface?
