The electric field 4cm from the wire is
Given:
charge is distributed uniformly along a long straight wire.
electric field 2cm from the wire is 20n/c
To find:
electric field 4cm from the wire
what is electric field?
Electric field is the region around charge particle or charged body in which if another charge is placed it experiences electrostatic force.An electric field is the physical field that surrounds electrically charged particles and exerts force on all other charged particles in the field, either attracting or repelling them.
thus the electric field 4cm from the wire is

Refer to the diagram shown below.
x = the distance (horizon) that you can see from the balloon,
Because the radius of the earth is 6400 km, and the balloon is 350 n above the earth's surface, therefore
h = 6400 + 0.350 = 6400.35 km.
From the Pythagorean theorem, obtain
x = √(6400.35² - 6400²) = 66.934 km
Answer: Your horizon is 66.934 km (or 66,934 m)
