Question

A circle of constant radius $3$k passes through $(0,0)$ and cuts the axes in A and B then the locus of centroid of triangle OAB is?

• A. $x^2+y^2=k^2$
• B. $x^2+y^2=2k^2$
• C. $x^2+y^2=3k^2$
• D. $x^2+y^2=4k^2$

Answer 1

The correct option is D $x^2+y^2=4k^2$

Hence, this is the answer.
