हिन्दीReferring to the geometric representation of the complex number \( z = x + iy \) in the Argand plane shown in the figure, what does the distance from the origin \( O(0,0) \) to the point \( P(x,y) \) represent?
View Answer & Solution
Correct answer · Option D
Modulus of \( z \)
Explanation
As shown in Fig. 4.2 of the text, the distance between \( P(x,y) \) and origin \( O(0,0) \) in the Argand plane is the modulus \( |z| = \sqrt{x^2 + y^2} \).
