Question

Assertion :If one end of the diameter of a sphere $x^2+y^2+z^2-8x-8y-6z+33=0$ is $(6,5,2)$, then other end is $(2,3,4)$ Reason: Centre ofthe sphere is the mid point ofthe end points of diameter of the sphere.

• A. Both Assertion & Reason are individually true & Reason is correct explanation of Assertion
• B. Both Assertion & Reason are individually true but Reason is not the ,correct (proper) explanation of Assertion
• C. Assertion is true but Reason is false
• D. Assertion is false but Reason is true

Answer 1

The correct option is A Both Assertion & Reason are individually true & Reason is correct explanation of Assertion

If one end of the diameter of a sphere $x^2+y^2+z^2-8x-8y-6z+33=0$ is $(6,5,2)$,

other end is $(2,3,4)$

$\therefore$ Assertion is correct

Also Reason correct since Centre of the sphere is the mid point ofthe end points of diameter of the sphere.

Hence Both Assertion & Reason are individually true & Reason is correct explanation of Assertion.
