AI Thread Summary
To determine how many electrons are missing from a positively charged oil drop, the charge on the drop (q) must be calculated using the weight (X N) and the electric field intensity (Y N/C). The formula q = Ne can be used, where N represents the number of missing electrons and e is the charge of a single electron. By dividing the total positive charge on the drop by the charge of one electron, the number of missing electrons can be found. This approach effectively relates the charge of the drop to the fundamental charge of electrons.

Homework Statement



A positive charge oil drop weights X N. An electric field intensity of YN/C suspends the drop. How many electrons is the drop missing?

X and Y are given though I don't need to give them because I am wondering what formula to use.,



The Attempt at a Solution



I have already found the charge on the drop as q. now how would I find the amount of missing electrons? I am solving for N I know.


Would I do this: q=Ne?

Thanks

Yes. The number of "missing" electrons is just the (+) charge on the drop divided by the charge on one electron.
 

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}...
