D. 20 N kg –1 WebOct 12, 2024 · It is defined as the gravitational force per unit mass experienced by a small test mass placed in the gravitational field. So if a test mass, m, experiences a force F at some point in space, then the field strength, g, at that point is given by g = F /m. Unit: The unit of Gravitational field strength g is N/kg, and it is a vector quantity.
