m ... v= 0 + q L Top view A small object is connected to a lightweight cord of length L =1.80 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 a mass m = 0.0100 kg, and the positive charge q is released from rest when the string makes an angle 0 = 60.0° with a uniform electric field of magnitude E = 260 V/m. The speed object when the string is parallel to the electric field is 0.274 m/s. Determine the charge of object.
