Question

What is the relation F=-eE..AND CONCEPT BEHIND IT

Answer 1

Sorry i dont know in which class do you read

Answer 2

Answer:

F=qE

Explanation:

This concept is used to deduce the formula for drift velocity

So, as the force applied on the electron is the opposite of electric field, then

F=-qE

and q=ne and the no of electron here is, n=1

so F=-neE

=> F=-eE
