Vedclass · Answer

(D) vector quantity is a physical quantity that has both magnitude and direction,and follows the laws of vector addition.Pressure is defined as force per unit area. Although force is a vector,pressure is a scalar quantity because it acts equally in all directions at a point in a fluid.Surface tension is defined as force per unit length,but it is a scalar quantity.Moment of inertia is a tensor quantity (specifically a second-rank tensor) that describes the resistance of an object to rotational motion.Since none of the given options are vector quantities,the correct answer is $D$.
