P and Q are centers of two circles whose radii are 7 cm and 3 cm, respectively. If the direct common tangents to the circles meet PQ extended at A, then A divides PQ _________.
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. externally in the ratio 7 : 3.
External division of PQ: According to properties of direct common tangents, A divides PQ externally in the ratio of the radii of the circles.
Hence, A divides PQ Externally in the ratio 7 : 3.
