If,
D=1.3361;
a=1.3361/J;
b=5/J;
z=(a/2)/sqrt(b)
For which values of J (z=0), (z=1), (z is >1) and (z is <1)? or
How can I find out the range of J?

 

plz help anybody

 

as from the equations: J=(1.3361/z)^2/20
and z=(D/2)/(5J)^0.5
as J is in the squareroot so J>0
and the other intervals of J will be determined by values of z
