The diagram shows a non-uniform electric field near a positively charged and a negatively charged sphere. Four electrons, A, B, C and D, are shown at different positions in the field. On which electron is the direction of the force on the electron shown correctly? [Figure 31.1]
AElectron A, with force vector pointing opposite to the electric field line
BElectron B, with force vector pointing along the electric field line
CElectron C, with force vector pointing along the electric field line
DElectron D, with force vector pointing perpendicular to the electric field line
