A charge of 38 pC is distributed on an isolated spherical conductor that has a radius of 4.4 cm . Point A is 2.5 cm from the center of the conductor and point B is 5 cm from the center of the conductor. Determine the electric potential difference VA − VB. The value of Coulomb’s constant is 8.98755 × 109 N · m2 /C 2 . Answer in units of V
