What is the electric field (given as a vector) at coordinates (x, y,z) = (1m,2m,2m) produced by a point charge of 4 μc sitting at the origin.

N/C

Solution:

Charge, Q =

Coordinates (x, y, z) are (1, 2, 2)

Now, we know that the Electric field at any point in the Cartesian plane is given by:

     (1)

where

d = distance of the charge from the point

Now, from eqn (1):

N/C

N/C

a lot of it means it can be "burned" for energy and sold at one price. if it is scarce, the price will go up

vapour or gas assuming atmospheriv pressure
