An electrically neutral model airplane is flying in a, Ask an Expert

Academics

An electrically neutral model airplane is flying in a horizontalcircle on a 3.0m guideline, which is nearly parallel to theground. The line breaks when the kinetic energy of the planeis 50.0 J. Reconsider the same situation, except that now there isa point charge of +q on the plane and a point charge of -q at theother end of the guideline. In this case, the line breaks when the kinetic energy of the plane is 51.8 J. Find the magnitude of the charges.
