I have one question.
What is Exact definition of the Vector Field Form Of an Eletric Field??
for exmple..
Vector Field
v^ (x,y,z)=yze_1 ^ +xze_2 ^ +xye_3 ^
i mean in physics They do all sorts of calculations
using the Electrical Field
but i can′t understand it
cus it′s such a Abstract concept
ex...▽^ ×E^ =−(∂B^ /∂t) or 𝚽=∮_A D∙dA=Q_0 ...etc
help me

held horizontal,one above the other in
a vacuum.Electrons having a speed of
6×10^6 m/s and moves normally to the
plates enter the region between them
through a hole in the lower plate which
is earthed.What potential must be
applied to the other plate so that the
electrons just fails to reach it?What
is the subsequent motion of these
electrons?

A +ve point charge of magnitude q is located on the y−axis
at a point of y=+d and another −ve charge of same magnitude
is located on the point y=−d.
A third +ve charge of same magnitude is located
at some point on x−axis.
(1)− what is the magnitude and direction of the force on
third charge ?
(a)− when its located on the origin.
(b)− when its coordinate is x.
(2)− show that when x is large compared to distance d,
the force in (b) is inversely proportionalto the
