Density can be calculated by dividing an objects mass by its volume.

. The mass is known but the volume needs to be calculated. The charge density formula is given by ρ q v 8 4 Charge density ρ 2 Cm3 Determine the charge density of an electric field if a charge of 6 C per metre is present in a cube of volume 3. The density of an object can be calculated by the formula.

The volume of a cube is length x width x height or 01 x 01 x 01 0001 meters 3. We have to find P 2 X 3. Integrating x 3 within the limits 2 and 3 gives the.
