Question 4 (1 point) What is not true about electric charges? O Negatively charged objects have a deficit of electrons O Every charged object creates an electric field of force in the space around it. 0 Electric charges exert forces on each other, even when they are not in contact. 0 Like charges repel, unlike charges attract. Question 5 (1 point) Gravitational field lines between two objects always 0 extend out of both objects 0 extend out of the object with more mass into the object with less mass 0 extend into both objects 0 extend out of the object with less mass into the object with more mass 0 go from the North pole to the South pole Question 6 (1 point) As the distance between two charges decreases, the electric potential energy of the two-charge system 0 always increases 0 increases if the charges have opposite signs, decreases if they have same signs 0 always decreases 0 increases if the charges have the same sign, decreases if they have opposite signs
