A coulomb net force question?

Question

A charge of +1 coulomb is placed at the 0-cm mark of a meter stick. A charge of -1 coulomb is placed at the 100 cm mark of the same meter stick. is it possible to place a proton somewhere on the meter stick so that the net force on it due to the charges at the ends is 0? If so, where should it be placed?

Answer 1

No. Because no matter *where* you put it, it will be attracted by the -1C charge, and repelled by the +1C charge.

HTH ☺
