Calculate the apparent electronic charge for each drop as follows:

Millikan determined the charge on the electron by studying the static charges on oil drops falling in an electric field. A student carried out this experiment using several oil drops for her measurements and calculated the charges on the drops. She obtained the following data:

Droplet | Calculated Charge (C) |

A | 1.60 x 10^{–}^{19} |

B | 3.15 x 10^{–19} |

C | 4.81 x 10^{–19} |

D | 6.31 x 10^{–19} |

What value should she report for the electronic charge?
