Electric Potential From Electric Field

AI Thread Summary
The discussion focuses on determining the point along the x-axis where the electric potential from two charges, q1 and q2, is zero, given that the electric field is zero at x=d/4. The participant suggests that since the electric field is zero at this point, the potential might also be zero there. They reason that electric potential is a scalar quantity and, if the charges are equal, the potential would cancel out at the midpoint between them. The conversation emphasizes the relationship between electric field and potential, highlighting that potential can be zero at points other than infinity. The conclusion suggests further exploration is needed to confirm if there are additional points where the potential is zero.

Homework Statement


Two particles, of charges q1 and q2 are separated by distance d. The net electric field due to the particles is zero @ x=d/4.
With V=0 @ infinity, locate (in terms of d) any point on the x axis (other than infinity) at which the electric potential due to the two particles is zero.


Homework Equations


V=-\int^{f}_{i} (\vec{E} \bullet d\vec{s})


The Attempt at a Solution


Seems too obvious to be true, but I think V = 0 @ d/4 since E=0 as well.
Anyone see where else is could be?

Pretend like the two particles are equidistant from the origin, therefore the origin is the middle of the two charges. When finding potential at a point, it is the potential of one charge on the point plus the potential of the other charge on the point. Potential is not a vector, so I believe if the charges are the same, you will find your answer in the middle of the two charges.
 

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}...
