A small plastic ball is connected to a lightweight cord of length L = 1.60 m that is tied to a point P, as shown in the figure. y = 0 + 9 L. Top view The ball, string, and point all lie on a frictionless, horizontal table. The ball has a mass m = 0.0100 kg, a charge q = +2.50 µc and is released from rest when the string makes an angle o = 60.0° with a uniform electric field of magnitude E = 320 V/m. Determine the speed (in m/s) of the ball when the string is parallel to the electric field. m/s Need Help? Read It
