Usually the force of gravity on electrons is neglected. to see why, we can compare the force of the earth’s gravity on an electron with the force exerted on the electron by an electric field of magnitude of 40000 v/m (a relatively small field). what is the force exerted on the electron by an electric field of magnitude of 40000 v/m? the acceleration of gravity is 9.8 m/s 2 , the mass of an electron is 9.10939 × 10−31 kg, and the elementary charge 1.602 × 10−19 c. answer in units of n.

Explanation:

The electric force exerted on the electron is given by:

where

is the magnitude of the electron charge

E = 40000 V/m is the electric field

Substituting,

By comparison, the gravitational force exerted on the electron is:

where

is the mass of the electron

g = 9.8 m/s^2 is the acceleration due to gravity

Substituting,

hi there!

your question asks at which segment does freezing occur.

since we're talking about water, the freezing point of water will be 32 degrees fahrenheit or below.

hope this ! ~

not too sure thinking all accelerations are pointed down
