Question

by applying electric field of the order of.....to a metal.electron can be pulled out of the metal

Answer 1

Answer:

Electric field of large magnitude is required to pull the electron out of the metal surface and the magnitude of electric field is of order

$E = 10^8 V/m$

Explanation:

When electron is pulled out of the metal due to strong electric field then this phenomenon is known as field emission

So here we can say that electric field must be sufficient high so that it can pull out the electron from the metal surface

this field is of order

$E = 10^8 V/m$

so the field strength of large magnitude is required to pull out the electron from surface of metal
