If magnitude of a complex number is tripled and is rotated anticlockwise by an angle , then resulting complex number would be:
Explanation for the correct answer:
We know that the magnitude of a complex number is given by
Given will be equal to
Now when a vector is rotated at an angle of , it will be given by
So, rotating at and tripling the magnitude, we get,
Therefore, option (A) is the correct answer.
