Question

An electron with a charge of -1.6 × 10-19 coulombs experiences a field of 1.4 × 105 newtons/coulomb. What is the magnitude of the electric force on this electron due to this field? 1.6 × 10-3 newtons 1.4 × 1024 newtons 2.2 × 10-14 newtons 7.4 × 10-13 newtons 4.5 × 1014 newtons

Answer 1

Electric force on this electron is
`F=2.2* 10^(-14)\ Newtons`

Step-by-step explanation:

It is given that,

Charge on an electron,
`q=-1.6* 10^(-19)\ C`

Electric field,
`E=1.4* 10^(5)\ N/C`

We have to find the magnitude of electric force on this electron due to this field. Mathematically, the electric force is given by :

F = q E

`F=1.6* 10^(-19)\ C* 1.4* 10^(5)\ N/C`

`F=2.24* 10^(-14)\ N`

or

`F=2.2* 10^(-14)\ N`

Hence, the correct option is (c) "
`2.2* 10^(-14)\ Newtons` "
