Electric fields, distance, and potential difference

AI Thread Summary
The discussion revolves around calculating the electric field between the plates of a TV set, given a potential difference of 20 kV and a distance of 1.0 cm. The correct formula to use is E = V/D, where E is the electric field, V is the potential difference, and D is the distance. A participant initially miscalculated the conversion of units but later confirmed their final answer as 2.0 x 10^6 N/C. The group consensus is that the calculations appear correct, but there is confusion about the expected answer.

Homework Statement



The potential difference between the accelerating plates of a TV set is about 20 kV. If the distance between the plates is 1.0 cm, find the magnitude of the uniform electric field in the region between the plates.



Homework Equations



V=ED so E=V/D where E is the electric field and D is the distance between the plates



The Attempt at a Solution



I am soooo confused. I swear I am just plugging in the numbers. since kv is 1000 v and cm is 1/100th of a m i did 20,000/.01 and that was wrong. I did this because they want the answer in N/C and i thought that conversion factor was right... any suggestions?

Your equation looks right to me. What did you get for a final answer? Did you include the units in your answer?
 
yes the units are already written after the equation. I got 2.0*10^6. after going over everything it looks right to me...
 
Yes, looks right to me too. Weird.
 
What's the answer supposed to be?
 

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}...
