At the three vertices of an equilateral triangle with side
a = 0.5 m
dotted
charges
Q1 = 2 μC, Q2 = −4 μC
and
3 Q = 7 μC. To calculate the resultant force,
which acts on the charge
Q3.
The dielectric constant for a vacuum
is
8.85 * 10^-12 C^2 / Nm. Draw the vectors of all forces.​

potential energy is directly proportional to height.

more height = more potential energy.

greatest increase in height = greatest increase in potential energy

where are the points with the greatest increase in height ?

has to be c-e or d-e .

d) physical means can be used to separate the components of air.

conduct current i mean it makes sense
