Question

A real value of x will satisfy the equation $|z| = 1$ $|z| > 1$ if.

• A. $|z_{1}| = |z_{2}| = .......... = |z_{n}| = 1,$
• B. $|z_{1} + z_{2} + z_{3} + ............. + z_{n}|$
• C. $|z_{1}| + |z_{2}| + ....... + |z_{n}|$
• D. $\left| \frac{1}{z_{1}} + \frac{1}{z_{2}} + ......... + \frac{1}{z_{n}} \right|$

Answer 1

Answer: (C)

$|z_{1}| + |z_{2}| + ....... + |z_{n}|$

Answer 2

$argz = \frac{5\pi}{6} = 150^{o}$. Taking modulus and squaring on both sides, $z = x + iy$.
