Answer:
a)  Eₓ = - A y + 2B x
, b)  Ey = -Ax –C
, c) Ez = 0
, d) The correct answer is 3
Explanation:
The electric field and the electric power are related
                     E = - dV / ds
a) Let's find the electric field on the x axis
                   Eₓ = - dV / dx
                   dV / dx = A y - B 2x
                   Eₓ = - A y + 2B x
b) calculate the electric field on the y-axis
                 Ey = - dV / dy
                 dV / dy = A x + C
                 Ey = -Ax –C
c) the electric field on the z axis
               dv / dz = 0
               Ez = 0
.d) at which point the electric field is zero
Since the electric field is a vector quantity all components must be zero
X axis
               0 = = - A y + 2B x
               y = 2B / A x
Axis y
              0 = -Ax –C
               .x = -C / A
We substitute this value in the previous equation
              .y = 2B / A (-C / A)
              .y = 2 B C / A2
The correct answer is 3
 
        
             
        
        
        
Answer:
The Balmer series refers to the spectral lines of hydrogen, associated to the emission of photons when an electron in the hydrogen atom jumps from a level  to the level
 to the level  .
.
The wavelength associated to each spectral line of the Balmer series is given by:

where  is the Rydberg constant for hydrogen, and where
 is the Rydberg constant for hydrogen, and where  is the initial level of the electron that jumps to the level n = 2.
 is the initial level of the electron that jumps to the level n = 2.
The first few spectral lines associated to this series are withing the visible part of the electromagnetic spectrum, and their wavelengths are:
656 nm (red, corresponding to the transition  )
)
486 nm (green,  )
)
434 nm (blue,  )
)
410 nm (violet,  )
)
All the following lines lie in the ultraviolet part of the spectrum. The limit of the Balmer series, corresponding to the transition  , is at 364.6 nm.
, is at 364.6 nm.
