Three charges are placed on the y-axis of a cartesian coordinate system, each charge has a value of 2.30 μC at positions and locations (0.00 cm, 2.00cm), (0.00 cm, 0.00cm), and (0.00 cm, -2.00cm). (a) What is the electric potential at point p; = (2.00cm, 0cm)? (b) What is the electric potential at point p = = (3.50cm, 0cm)? (c) What is the change in potential, AV, between points p; and pf (d) What is the change in potential energy for a 1.40 μC charge with mass 1700g that moves from point p; to pf? Use your result from (c) (e) If the charge from (d) starts from rest what is its speed at point pr? (f) Repeat part (d) and (e) with a 2.50 μC instead and the same HHOHOHOH 91 93 Pi Pf

Expert Solution
Step 1
Solution:
The electric potential at a distance r from the charge q is given by,
The position of the charges and the point pi and pf are also given.
The potential at Pi is the sum of the algebraic sum of potential due to the individual charge.
