Thank you for the opportunity to help you with your question!

one electron has charge -1.6 x 10^(-19) coulumb.

Net charge of 1.4x10^7 electrons is 1.4x(-1.6)x10^(7)x10^(-19) coulomb, that is,-2.24x10^(-12) coulomb.

Thus ,net charge of 1.4x10^7 electrons is -2.24x10^(-12) coulomb.

Kindly do ask me if any thing unclear. 


Please let me know if you need any clarification. I'm always happy to answer your questions.
