A small plastic ball is connected to a lightweight cord of length L-1.40 m that is tied to a point P, as shown in the figure.
The ball string and point all lie on a frictionless, horizontal table. The ball has a mass m = 0.0100kg, a charge q = +2.10 C and is released from rest when the string makes an arigle θ = 60.0° with a uniform
electric field of magnitude E= 350 V/m. Determine the speed (in m/s) of the ball when the string is parallel to the electric fleld.

A small 12.6 g plastic ball is tied to a very light 28.4 cm string that is attached to the vertical wall of a room.
A small 12.6 g plastic ball is tied to a very light 28.4 cm string that is attached to the vertical wall of a room. (See the figure (Figure 1).) A uniform horizontal electric field exists in this room. When the ball has been given an excess charge of -1.10μC , you observe that it remains suspended, with the string making an angle of 17.4° with the wall. Part A Find the magnitude of the electric field in the room. Part B Find the...
