Let \((3,4,-1)\) and \((-1,2,3)\) be the end points of a diameter of a sphere. Then, the radius of the sphere is equal to
- A 2 units
- B 3 units
- C 6 units
- D 7 units
Answer & Solution
Correct Answer
(B) 3 units
Step-by-step Solution
Detailed explanation
Let \(P(3,4,-1)\) and \(Q(-1,2,3)\) be the end points of the diameter of a sphere. \(\therefore\) Length of diameter \(=P Q\)…
