50 μC of negative charge is placed on an insulating pith ball and lowered into an insulating plastic container, suspended from an insulating thread attached to the lid of the box. After the box is entirely sealed, the electric flux through the sides of the box is: 5.65×106 N⋅m2/C. 5.65×105 N⋅m2/C. −5.65×105 N⋅m2/C. Can't tell unless the dimensions of the box are given. −5.65×106 N⋅m2/C
