MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER The charge density on a disk of radius R = 12.2 cm is given by o = ar, with a = 1.42 pC/m and r measured radially outward from the origin (see figure below). What is the electric potential at point A, a distance of 48.0 cm above the disk? Hint: You will need to integrate the nonuniform charge density to find the electric potential. You will find a table of integrals helpful for performing the integration. X Your response differs significantly from the correct answer. Rework your solution from the beginning and check each step carefully. V R Submit
