A small object is connected to a lightweight cord of length L=1.20 m that is tied to a point P, as shown in the figure. The object, string, and point all lie on a frictionless, horizontal table. The object has mass m=.0100kg and charge q= 2.10 uC and is released from rest when the string makes an angle theta=60 with a uniform electric field of magnitude E=260 V/m. Determine the speed in m/a of the object when the string is parallel to the electric field.
