21. The 60-g banana-shaped earring illustrated below is suspended in midair in electro- static equilibrium. The earring is connected to the floor by a thread that makes a 60° angle with the vertical. The earring has a charge of +300 µC and there is a uniform electric field directed 60° above the horizontal. (A) Draw a FBD for the earring. Label each force and the x- and y-coordinates. 60° 60° (B) Write the x- and y-sums for the forces acting on the earring. There will be two sums. On the line immediately below each sum, rewrite the left-hand side in terms of the forces. (C) Determine the magnitude of the electric field.
