Question

how can we get electric field from electric potential?

Answer 1

\[V=E.d\]

Answer 2

too*there is one eq of maxwell too but i dont remember

Answer 3

\[Vab=Va-Vb=\int\limits_{a}^{?b}Edl\]

Answer 4

from that formula

Answer 5

your E is a constant in thah line?

Answer 6

yep

Answer 7

take it off \[E.\int\limits_{a}^{2.b}dl=E(2.b-a)\]

Answer 8

where is electic potential?

Answer 9

you said Vab=E(2.b-a)

Answer 10

oh i get it thanks.

Answer 11

A point charge Q is located at the center of a cube of side L. In
addition, six other identical point charges q inside the cube are
positioned symmetrically around Q, as shown in Fig. 4.
Determine the electric flux through one face of the cube.
