The plane touches the sphere iff it's perpendicular distance from centre is equal to radius.Thus,Distance=K/rt3=radius=KK=0

But when K=0,the sphere reduces to a point (0,0,0) And the plane reduces to x+y+z=0 which passes thro the origin.

What's the ans given,no value of k, is it?
MAKING A MISTAKE IS HUMAN BUT REPEATING IT IS IDIOTIC.
