Part A -7 A small sphere with mass 5.00x 10 kg and charge +8.00 µC is released from rest a distance of 0.300 m above a large horizontal insulating sheet of charge that has uniform surface charge density o = +8.00 pC/m2. Using energy methods, calculate the speed of the sphere when it is 0.100 m above the sheet. Express your answer to three significant figures and include the appropriate units. HA Value Units
