Ans: E
Question: How to solve this kind of problem?

Ans: B
My approach: As the angle POQ=90, t should be equal to 1. If P is at that point, radius of circle should be 2. As radius of circle OQ should also be 2, it can be 2, if x-axis length of OQ=root (3). my answer was D.

Hi Hai1

I believe you'll receive more responses if you create a unique thread for each question.
Otherwise, you end up with 6 sets of discussions all on the same thread. It gets pretty confusing.

Cheers and welcome,
Brent
