A particle having charge q=+2.00 micro coulomb and mass m=0.010 kg is connected to a string that is L=1.50 m long and tied to the pivot point P in the figure. The particle, string, and pivot point all lie on a frictionless, horizontal table The particle is released from rest when the string makes an angle With a uniform electric field of magnitude E=300 V/m. Determine the speed of the particle went the string is parallel to the electric field.
