Which of the following statements are true consequences of the principle of superposition?
(i) the net electric force on a charge, q_0q 0 , due to other nearby charges is the vector sum of the individual electric forces on that charge.
(ii) the individual forces on a charge, q_0q 0 , can be summed by vector addition in any sequential order to find the net force on charge q_0q 0 .
(iii) a charge, q_0q 0 , placed at the exact midpoint between two identical charges will experience zero net force due to those charges.
(iv) the net force on a charge, q_0q 0 due to other nearby charges is exactly equal to the force on charge q_0q 0 due to the charge nearest to it, and is not affected at all by any of other charges nearby.
