Q. Two particles of charge Q(-L,0) and nQ(αL,0) where n = 10. When a third charge is placed at the origin, it is found that the force on it is zero. Find α.

Q. Two forces FA and FB are applied to an object whose mass is 16.7 kg. The larger force is FA. When both forces point due east, the object's acceleration has a magnitude of 0.859 m/s2. However, when FA points due east and FB points due west, the acceleration is 0.500 m/s2, due east. Find (a) the magnitude of FA and (b) the magnitude of FB.
