Question

A small sphere of charge q = +65 µC and mass m = 5.5 g is attached to a light string and placed in a uniform electric field E that makes an angle θ = 42° with the horizontal. The opposite end of the string is attached to a wall, and the sphere is in static equilibrium when the string is horizontal, as shown in the figure below. (b) Find the magnitude of the electric field. (c) Find the tension in the string. (Enter the magnitude of the tension in the string.)

Step 1

- The gravitational force \( F_g = mg \) acts downward. - The electric force \( F_e = qE \) acts at an angle \( \theta = 42^\circ \) with the horizontal. - The tension \( T \) in the string acts horizontally to the left. Show more…
