Answer 1

Answer:

If a point is on the y-axis, then x-coordinate and the z-coordinate of the points are zero.

Let A(0,b,0) be the point on the y-axis at a distance of 5

2

from point P(3,−2,5).

Accordingly, AP=5

2

⇒AP

2

=50

⇒(3−0)

2

+(−2−b)

2

+(5−0)

2

=50

⇒9+4+b

2

+4b+25=50

⇒b

2

+4b−12=0

⇒b

2

+6b−2b−12=0

⇒(b+6)(b−2)=0

⇒b=−6 or 2
