0. 1.9 Charge Cube Eight charges ( 50C each) are arranged on the corners of a cube side length 1cm. What is the magnitude of the force on each charge in Newtons? Hint: Abjection of Inspection. 9. 1.8 Hanging Charges Two identical spheres of charge q and mass m are each hanging from strings and are at equilibrium as shown below: Give an expression for tan in terms of ke (type "k_e"), q,m,g, and d (the distance between the spheres)
