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.

The electric force depends on which two factors?

• The size of the charges and the distance between the charges

• The type of magnetic pole and the distance between the charges

• The mass of the objects and the distance between the objects
