Two small, identical spherical conductorscarry charges of 5.1 μC and 2.3 μC. They are separated by adistance of 52.0 cm. Calculate the magnitude of the electrostaticforce between these two spheres.
How are you supposed to calculate themagnitude if there is no given angle? I dont know if these twocharges lie on a line or within the points of a triangle? Pleasehelp!
