An electrically neutral model airplane is flying in a horizontal circle on a 2. 5-m guideline, which is nearly parallel to the ground. The line breaks when the kinetic energy of the plane is 50 J. Reconsider the same situation, except that now there is a point charge of +q on the plane and a point charge of -g at the other end of the guideline. In this case, the line breaks when the kinetic energy of the plane is 53. 0 J. Find the magnitude of the charges. q= i__________ С
