1.	If two forces magnitude F each are acting in the Cartesian coordinate and are acting at the points A(3,3) and B(-3,3). They are heading towards negative z direction and positive z direction respectively. The distance between them is given as r. The radius vectors of the force at A and B are Ra and Rb respectively. Then the moment is given as:
A.	(Ra-Rb).F
B.	(Rb-Ra).F
C.	(Ra-Rb)xF
D.	(Rb-Ra)xF
