Three circles C1,C2 and C3 with radii r1,r2 and r1+r2 respectively are such that C1 and C2 touch each other externally and C3 internally. Another circle with radius r3 touches all the three circles. If r1>r2>r3 and r1,r2,r3 are in A.P. then (r1r2)3 isQ. Circles C1 & C2 externally touch each other and they both internally touch another circle C3. The radii of C1 & C2 are 4 and 10 respectiveley, and the centers of the three circles are collinear. A chord of C3 is a transverse common tangent to the circles C1 and C2. Find the length of the chordQ. Let C1,C2 be two circles touching each other externally at the point A and let AB be the diameter of circle C1. Draw a secant BA3 to circle C2, intersecting circle C1 at a point A1(≠A), and circle C2 at points A2 and A3. If BA1=2, BA2=3 and BA3=4, then the radii of circles C1 and C2 are respectively.Q. C1 and C2 are two non concentric fixed circle with radii R1 and R2 such that R2 is contained in C1. A third circle C moves in such a way that it touches C1 internally and C2 externally, then find the locus of its centre. Q. Let circles C1 and C2 on Argand be given by |z+1|=3 and |z−2|=7 respectively. If a variable circle |z−z0|=r be inside circle C2 such that it touches C1 externally and C2 internally then locus of 'Z0' describes a conic E whose eccentricity is equal to :View MoreJoin BYJU'S Learning ProgramGrade/Exam1st Grade2nd Grade3rd Grade4th Grade5th Grade6th grade7th grade8th Grade9th Grade10th Grade11th Grade12th GradeSubmitsimilar_iconRelated VideosthumbnaillockEllipse and TerminologiesMATHEMATICSWatch in Appexplore_more_iconExplore moreGeneral Equation of EllipseStandard XII MathematicsJoin BYJU'S Learning ProgramGrade/Exam1st Grade2nd Grade3rd Grade4th Grade5th Grade6th grade7th grade8th Grade9th Grade10th Grade11th Grade12th GradeSubmitbook_imageAI Tutorbook_imageTextbooksbook_imageQuestion Papersbook_imageInstall appCrossIcon
