The definition of gravitational field strength is:

• The region of space surrounding a body where other bodies will feel an attractive force due to it.
• The region of space surrounding a body where other bodies will feel an repulsive force due to it.
• The region of space surrounding a charge where other charges will feel an attractive force due to it.
• The region of space surrounding a charge where other charges will feel an repulsive force due to it.
