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

Answer:

Electric force on this electron is $F=2.2\times 10^{-14}\ Newtons$

Explanation:

It is given that,

Charge on an electron, $q=-1.6\times 10^{-19}\ C$

Electric field, $E=1.4\times 10^{5}\ N/C$

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

$F=1.6\times 10^{-19}\ C\times 1.4\times 10^{5}\ N/C$

$F=2.24\times 10^{-14}\ N$

or

$F=2.2\times 10^{-14}\ N$

Hence, the correct option is (c) " $2.2\times 10^{-14}\ Newtons$ "
