The three q1=q2=q3 = 14 μC charges came into the arrangement shown below from very far apart. q1 is located at (0.00, 5.2) cm, q2 is located at (0.00, -5.2) cm and q3 located at (13.26, 0.00) cm a) How much work must be done to move the three charges into the arrangement shown if they started very far apart?  b) What is the work if the particle on the right, q3, with mass 49.5 g, is released from rest and allowed to move freely to point P, twice 13.26 distance, figure below? c) How fast, in m/s, is q3 moving when it has moved to point P, twice 13.26 distance? To continue, please submit the result of part (c) in units of m/s.   Round your answer to 0 decimal places.

Resources LX Give U A particle that carries a net charge of –77.8 µC is held in a constant electric field that is uniform over the entire region. The electric field vector is oriented 25.2° clockwise from the vertical axis, as shown in the figure. If the magnitude of the electric field is 9.82 N/C, how much work is done by the electric field as the particle is made to move a distance of d = 0.156 m straight up? d 25.2 work: J What is the potential difference AV between the particle's initial and final positions? AV = V
