If the system of equations
x=a(y+z),y=b(z+x),z=c(x+y)
have non-trivial solution and (a,b,c -1) then
a/1+a + b/1+b + c/1+c =

A disc of radius R has a light pole fixed  to the disc at the circumference which in turn has a pendulum of lenght R attached to its other end.The disc is rotated with a constant angular velocity w.the string is making an angle 30 with teh rod .The angular velocity w of the disc is
a) g [ 2] 3 1/2
-------
R
b) g[2 ] 3 1/2
-------
2R
c) g 1/2
-------
