Calcula la intensidad de la fuerza que ejercen mutuamente las siguientes cargas puntuales si están en el aire: q1= -4,5•10^-6 y q2=+9,8•10^-6C

The path of a satellite orbiting the earth causes it to pass directly over two tracking stations a and b, which are 51 miles apart. when the satellite is on one side of the two stations, the angles of elevation at a and b are measured to be 87 degrees and 84 degrees, respectively. (a) how far is the satellite from station a? (b) how high is the satellite above the ground?
