Question

The equation of the circle and its chords are respectively x² + y² = a² and x cos α + y sin α = p. The equation of the circle of which this chord is a diameter, is 

(a) x² + y² - 2px cos α - 2py sin α 2p² - a² = 0

(b) x² + y² + 2px cos α + 2py sin α + 2p² - a² = 0

(c)  x² + y² - 2ps cos α - 2py sin α + p² - a² = 0

(d) None of the above

Answer 1

Correct option (a) x² + y² - 2px cos α - 2py sin α 2p² - a² = 0
