1. The problem statement, all variables and given/known data

We have the setup shown in the figure (see this figure). It rotates with angular velocity ω counter clockwise. ¿Power radiated by the system? (Sorry if it's not the correct translation -- Potencia radiada in spanish).

2. Relevant equations

$P_{rad}=\frac{μω^{4}p^{2}}{12πc}$

3. The attempt at a solution

The dipoles 1 and 2 can be written (module) as p=lq=√2q. Can be split in its x and y components:

Dipole 1

p_x = √2q cos (ωt + 45)
p_y = √2q sin (ωt + 45)

Dipole 2

p_x = √2q cos (ωt - 45)
p_y = √2q sin (ωt - 45)

Dipole 3 (given)

p_y = p sin (ωt + 90)

Now, since they do not interfiere between them (orthogonal), we can write

$p^{2} = p^{2}_{x} + p^{2}_{y}$

in the equation for P.

Is this correct? Thanks!
