A charged particle is connected to a string that is is tied to the pivot point P. The particle, string, and pivot point all lie on a horizontal table (consequently the figure below is viewed from above the table). The particle is initially released from rest when the string makes an angle 29◦ with a uniform electric field in the horizontal plane (shown in the figure). Determine the speed of the particle when the string is parallel to the electric field.Answer in units of m/s.
