6.30. Model: The plastic ball is represented as a particle in static equilibrium. Visualize:Solve: The electric force, like the weight, is a long-range force. So the ball experiences the contact force of the string’s tension plus twolong-range forces. The equilibrium condition is ()( )() ()netelecelecnetGsin0 Ncos0 N
