1. The problem statement, all variables and given/known data
If the Superkamiokande neutrino detector could accurately determine the direction of detected neutrinos, what would the angular diameter, in arcminutes, be of the neutrino emission as seen from Earth.
Assume all the neutrinos are ^{8}B neutrinos with energies <14.02MeV.
2. Relevant equations
\delta = 2tan^{-1}(\left \frac{0.5 d}{D} \right)
Where d = visual diameter
D = distance to the object.
3. The attempt at a solution
D = The distance from the sun to the earth = 1.5x10^8 km.
I can't work out what the value of d would be, and how I can use the value of neutrino energies in working this out.
Is there a different equation that I can use?
