Q1. (a)Forces F₁ = 3x - j7 , F₂ = 2 - j5y , F₃ = - 19 + j2x and F₄ = - 2y + j3 are

represented by complex numbers in rectangular form.

Given that the four forces are in equilibrium, determine the value of EACH of the real numbers in x and y. (8)

(b) The impedance, z, of an electronic circuit is given by z = 5 - j12and the current i , is given by i = 10 - j.

Determine, in polar form, the voltage, v, across the impedance, given that v = iz. (8)
