Verified Answer
A point z = P(x,y) lies on the negative direction of y axis, so amp(z)...
P(-x,-y) lies on the 3rd or 4th quadrant
So, according to the question, points lies in 3rd quadrant
i.e. 3(π/2)

A point z = P(x,y) lies on the negative direction of y axis, so amp(z)...
The amplitude of a complex number is the distance from the origin to the point representing the complex number in the complex plane. In this case, since the point lies on the negative direction of the y-axis, the x-coordinate would be 0 and the y-coordinate would be negative.

Therefore, the point would be represented as z = 0 - yi, where y is a positive value. The distance from the origin to this point is the absolute value of the y-coordinate, which is the amplitude.

So, the amplitude of z is |y|.
