I `|z|ge5` then the least value of `|z+ 2/z|` is (A) `23/5` (B) `24/5` (C) `5` (D) none of these

If |z| ge 5 , then least value of |z - (1)/(z)| is

If |z-4+3i|le3, then the least value of |z|= (A) 2 (B) 3 (C) 4 (D) 5

If |z|ge3, then determine the least value of |z+(1)/(z)| .

If |z-4/z|=2 then the greatest value of |z| is (A) sqrt(5)-1 (B) sqrt(5)+1 (C) sqrt(5) (D) 2

If |z-4/2z|=2 then the least of |z| is (A) sqrt)5)=-1 (B) sqrt(5)-2 (C) sqrt(5) (D) 2

If |z|+z=3+i , then value of |z| is (A) 5//3 (B) 3//5 (C) 4//3 (D) 3//4

If |z-5i|=|z+5i, then the locus of z

If |z+2+3i|=5 then the locus of z is

Number of solutions of Re(z^2)=0 and |z|=rsqrt(2) where z is a complex number and rgt0 is (A) 2 (B) 4 (C) 5 (D) none of these
