Imagine that you have a glass of water in which all of the water molecules are aligned, so that their positive ends all point upwards. Imagine that each molecule can be treated as a simple dipole consisting of two charges (1 and —q separated by a small vertical distance a. In this case, the water is like two superimposed charge densities, one positive and one negative, displaced vertically by a tiny distance a. If the water in a glass is in this aligned state, what is the magnitude of the electric ?eld E in the water? Your answer should depend on the product go, which is the dipole moment of the water molecule, which you can look up (be careful with units!). What would be the potential difference V in volts from the top to the bottom of a pint glass of water in this aligned state? Do you think this ever happens in nature? Clearly state all your assumptions, approximations and estimates.

In real life water molecules does not behave in this manner. They will never orient themselves because in this assumption there is layer of positive charges followed by layer of negative charges. Within a layer there will be high value of repulsive force hence water glass will he unstable.
Step-by-step explanation
Problem - 1 +9 0 9-31 -9 edoctorie field at Point P due to +9 change is furom coulomb's law is E,
Kq wy 2 electric field at pount p due to - 9 change i's E , ( 9 - 07 ) 2 mow we drink both fields at
point p is VE a
net field at point P is E = E, + EQ = Kq + Kq E 47 ? (9-57) ? E kq ( 9 - UT ) + up ? T ? ( 9 - 01 ) ? E =
Kq ( 93 + ? - 2901 + 01?) ? (9 - 01 ) 2 E = Kq ( 9? + 207 7 - 29NT ) VT ? ( 9 - 07 ) 2 E = K ( 29? + 9.
PUT ? - 201 29 ) Up ? ( 9 - 01 ) 2
Electric butwren platy from Graves's law E = ro gradient of alecturec potential is called electric tila
that is V : E.q 29
