Two identical small charged spheres A and B, each having a mass of m and a charge q, hang in equilibrium as shown in the Figure. The length of each string is L, and the it forms an angle 8 with vertical direction. a) [10% ] How many total force onto the B object? b) [10% ] What is the tension force direction of the string onto B? c) [10% ] What is the electric force direction onto B? d) [35%] Write the equation when the B object is under equilibrium in the horizontal direction: e) [35%] Write the equation when the B object is under equilibrium in the vertical direction: 0 L B
