If |z|= maximum `{|z+2|,|z-2|}`, then` (A) `|z-`barz`|`= `1/2` (B) `|z+`barz`|=4` (C) `|z+`barz`|= 1/2` (D) `|`z-barz`=2

if z=3 -2i, then verify that (i) z + barz = 2Rez (ii) z - barz = 2ilm z

If |z+barz|+|z-barz|=2 , then z lies on

If |z+barz|+|z-barz|=8 , then z lies on

If |z_1+z_2|=|z_1-z_2| and |z_1|=|z_2|, then (A) z_1=+-iz_2 (B) z_1=z_2 (C) z_=-z_2 (D) z_2=+-iz_1

If kgt1,|z_1|,k and |(k-z_1barz_2)/(z_1-kz_2)|=1 , then (A) z_2=0 (B) |z_2|=1 (C) |z_2|=4 (D) |z_2|ltk

If z_(1) = 3+ 2i and z_(2) = 2-i then verify that (i) bar(z_(1) + z_(2)) = barz_(1) + barz_(2)

If z_1 and z_2 are two complex numbers such that |(barz_1-2barz_2)(2-z_1barz_2)|=1 then (A) |z_1|=1, if |z_2|!=1 (B) |z_1|=2, if |z_2|!=1 (C) |z_2|=2, if |z_1|!=1 (D) |z_2|=1, if |z_1|!=2

Find the complex number z if zbarz = 2 and z + barz=2

Which of the following is (are) correct? (A) barz_1+abarz_2=2b (B) barz_1+abarz_2=b (C) barz_1+abarz_2=-b (D) barz_1+abarz_2=-2b

If z is a non zero complex, number then |(|barz |^2)/(z barz )| is equal to (a). |(barz )/z| (b). |z| (c). |barz| (d). none of these
