JEE Main Physics Kinematics

Consider three vectors vector A, vector B, vector C. It is given that vector A and vector B lie in the x-y plane and the direction of vector C is along (+k^). Also, it is known that |vector A|=10 and |vector B|=6 units and the three vectors are related by the relation vector A=vector B - alpha(vector B X vector C), where alpha is some postive constant. Now, if only the magnitude of vector C is doubled, then what should the magnitude of vector B be, for which vector A remains unchanged (both in magnitude and direction)?
