An electron is placed in an electric field of strength 300 N/C. What is the magnitude of the force the electron experiences?(adsbygoogle = window.adsbygoogle || []).push({});

1.6x10^13 N

2.4x10^13 N

3.2x10^14 N

4.8x10^14 N

6.4x10^14 N

A particle of mass 0.005 kg is given a charge of +4.0 µC and is placed in an electrical field that is directed antiparallel to the earth's gravitational field. What is the field strength, expressed in N/C, if it balances the weight of the particle?

1.6 x10^6

2.4 x10^6

3.2 x10^6

4.4 x10^6

4.7 x10^6

Wen I tried to do these questions, I did not even come close to the figure in bold. I thought F = Eq or F = mg/q would be sufficient enough, but I guess not. Can anyone explain how to arrive at each answer?

Thanks.
