JEE MainMathematicsCircleNumerical+4 / −1
Let P(a1,b1)P\left(a_1, b_1\right)P(a1​,b1​) and Q(a2,b2)Q\left(a_2, b_2\right)Q(a2​,b2​) be two distinct points on a circle with center C(2,3)C(\sqrt{2}, \sqrt{3})C(2​,3​). Let O\mathrm{O}O be the origin and OC\mathrm{OC}OC be perpendicular to both CP\mathrm{CP}CP and CQ\mathrm{CQ}CQ. If the area of the triangle OCP\mathrm{OCP}OCP is 352\frac{\sqrt{35}}{2}235​​, then a12+a22+b12+b22a_1^2+a_2^2+b_1^2+b_2^2a12​+a22​+b12​+b22​ is equal to :
