Question

Find the force that an electron experience in an electric field of 1000NC. If
the electron is free to move. Find the distance covered by it in 10ns. The mass
of electron is 9.11x10-31 kg.​

Answer 1

Correct option is

A

5.62×10−11N/C

Weight of 1 e−=mg

=9×10−31×10

=9×10−30

We know force F=Eq

⇒Eq=9×10−30

⇒E=1⋅6×10−199×10−30

⇒E=5⋅62×10−11N/C.
