1.	Is torque a vector or a scalar? If it is a vector give its direction.
Answer» SOLUTION :TORQUE is a vector. Torque`vectau=barrxxbarF` .The direction of torque is PERPENDICULAR to the PLANE containing `barr` and `barF`. If `barr` and `barF` and in X-Y plane then torque is along Z-axis. Its direction is given by right hand screw rule.
