The potential difference and the electric field - please check my answer

AI Thread Summary
The potential difference across a 2-meter stick in a uniform electric field is given as 400V. The initial calculation for the electric field strength using the formula E = V/d results in 200 V/m. However, the correct answer is 800 V/m, indicating a misunderstanding in the application of the formula. The confusion arises from the relationship between potential difference, electric field, and distance. Clarification on the proper use of the formula E = V/d is necessary to resolve the discrepancy.

Homework Statement



The potential difference between the ends of a 2 meter stick that is parallel to a uniform electric field is 400V. The magnitude of the electric field is:

Homework Equations



V = E.d

The Attempt at a Solution


E = v/d = 200 v/m
The right answer
is 800 v/m, my understanding is U= qV= Fd therefore qV= Eqd and E = V/d so I don't know how they came up with this answer (800v/m)

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}...
