The force between electric charges depends on...
the mass of the charges
the distance between charges
the amount of charge
the velocity of the charges
A(n) (a) is a material through which electrons (and therefore charge) move easily.
A(n) (b) is a material through which electrons (and therefore charge) do not move easily.
Copper is an example of a(n) (a)
Rubber is an example of a(n) (b)
I touched a negatively charged rod to a neutral object, and some negative charge was transferred to the object. This is an example of...
charging by induction
charging by friction
charging by contact
charging by polarization
I bring a positively charged rod near a neutral metal sphere, which causes the negative charge within the sphere to move toward the rod, and the positive charge to move away from the rod. This is an example of...
