An electron travels 0.01 m across an electric potential difference of 6 x 10^6 V. What is the force exerted on the electron? Type your answer below including the correct units

Explanation:

The force experienced by a charged particle immersed in an electric field is

where

q is the charge of the particle

E is the strength of the electric field

For a uniform field, we can write

where

is the potential difference

d is the distance travelled

So we can rewrite the force as

In this problem:

is the charge of the electron

is the potential difference

d = 0.01 m is the distance covered

Substituting, we find the force:

because growing process had stoped after 4-5 year

r = ρ x length / area  

ρ = r x area / length  

ρ is in ohm-meters  

in basic units, it is m³kg/s³a²  

i think this is it.
