Thanks Mr Woon Kiat. Yes, part b solution is good and I understand :)
But the model answer for part c is 1/sqrt2 q. Could you help to review it again and advise? Many thanks !

Part c has a slight misspelling.
Yup. I think I made a mistake.
Since the vectors are parallel, their ratio would be
|BD| / |AE| = sqrt2 / 2
BD = (sqrt2 / 2) * AE
BD = (sqrt2 / 2) q
I believe Mr Eric gave a good explanation in his answer.

Thank you for coming back to me Mr Woon Kiat. Really appreciated. I hope you have a good day ahead :)
