Identify the vector quantity among these listed physical quantities?

The vector quantity among the listed physical quantities is Gravitational Intensity. Here's why: 1. Energy: Scalar quantity. It has magnitude but no direction. 2. Mass: Scalar quantity. It has magnitude but no direction. 3. Density: Scalar quantity. It has magnitude but no direction. 4. Gravitational Intensity: Vector quantity. It has both magnitude and direction, as it represents the gravitational force per unit mass at a point in space. So, the correct answer is Gravitational Intensity.
