OA=√(2)2+(2)2=2√2,px= OAcos90=0,py=psin90=2√2j.coz Paid rotated by 45 and then theta will become 90° hope it would help you

That was quite a great digramatic answer.
 
body,div,table,thead,tbody,tfoot,tr,th,td,p { font-family:"Arial"; font-size:x-small } a.comment-indicator:hover + comment { background:#ffd; position:absolute; display:block; border:1px solid black; padding:0.5em; } a.comment-indicator { background:red; display:inline-block; border:1px solid black; width:0.5em; height:0.5em; } comment { display:none; }

Here the magnitude of the vector is 2√2.. And the magnitude is not changing .... The direction is changing ... The new direction is along the +ve y axis ... And magnitude is same .. So the vector is =
2√2j
