Two circles with different radii touch each other in one point such that the smaller circle lies completely inside the larger circle. The smaller circle has point O as the center. A chord AB of the larger circle is tangent to the smaller circle. AB touches smaller circle at point C. A and B lies on the circumference of the larger circle. If BC = 10 cm and OB = 20 cm. Find OC (in cm).

AB touches smaller circle at C. So, OC ⊥ AB.
Now, in AOCB, OB = 20 cm and BC =10 cm. By pythagoras theorem we get, OC = 10√3 cm
Hence, option 1.
