OA and OB are two perpendicular rays. There will be exactly one point which is 2 cm away from OB and 3 cm away from OA.
True
There will be infinite points which will be 2 cm away from OB, but it is also said that the given point is 3 cm from OA. So, there can be only one point which is 2 cm away from OB and 3 cm away from OA. So, the given statement is true.
