A particle having charge q = +2.50 µC andmass m = 0.0100 kg is connected to a string that isL = 1.20 m long and is tiedto the pivot point P. The particle, string, and pivotpoint all lie on a frictionless horizontal table. The particle isreleased from rest when the string makes an angle θ= 60.0° with a uniform electric field of magnitude E =340 V/m. Determine the speed of the particle when the string is parallel to the electric field (pointa in the figure).
