The charge per unit length on a long, straight filament is-92.0 μc/m. (a) find the electric field 10.0 cm from the filament, where distances are measured perpendicular to the length of the filament. (take radially inward toward the filament as the positive direction. mn/c (b) find the electric field 46.5 cm from the filament, where distances are measured perpendicular to the length of the filament. mn/c (c) find the electric field 130 cm from the filament, where distances are measured perpendicular to the length of the filament. mn/c

E(0.1m)=-16.53.10^6 V.m

E(0.465m)=-3.55.10^6 V.m

E(1.3m)=-1.27^6 V.m

Explanation:

You can find the field using Gauss's Law:

the surface S is an "infinite long" cylinderr of radio r.

E(r)=

λ=-92.0 μC/m, ε=8.85.10^-12

E(0.1m)=-16.53.10^6 V.m

E(0.465m)=-3.55.10^6 V.m

E(1.3m)=-1.27^6 V.m

answer: the metamorphic rocks are formed when they are exposed to high pressure and high temperatures. this happens when one of the earth's plates comes in contact with the other plate by traveling in opposite directions, straight into each other or slipping under one another. the friction that is caused by this activity results in   melting of rocks and when it cools they are known as metamorphic rocks. this process needs a controlled amount of pressure and temperature otherwise it may turn into magma.
