Athin ball shell is shaped like a hollow ball with a radius of 42.8 cm. the material is a conductor with charge 0.8 nc a point charge of -5.4 nc is placed in the center of the ball. how many n / c is the electric field just outside the ball? remember positive is outwards i did this: got total charge qencloced = -4.6*10^-9 c found the field e=(qencloced/epsilon) divided by 4*pi*speed squared got 225.80 n/c. the answer in my (really annoying online test) is 265 n/c
