What is the centre of the sphere `ax^2+by^2+cz^2-6x=0` if the radius is 1 unit?

(0,0,0)

(1,0,0)

(3,0,0)

cannot be determined as values of a,b,c are unknown

Text Solution

Verified by Experts

The correct Answer is:

In the given equation, there are three unknown parameters and no equation has been given to evaluate those, hence centre of sphere cannot be determined.
