An infinite sheet of charge is located in the y-z plane at x = 0 and has uniform charge denisity σ1 = 0.25 μC/m2. Another infinite sheet of charge with uniform charge density σ2 = -0.42 μC/m2 is located at x = c = 36 cm.. An uncharged infinite conducting slab is placed halfway in between these sheets ( i. e., between x = 16 cm and x = 20 cm). 1)What is Ex(P), the x-component of the electric field at point P, located at (x, y) = (8 cm, 0)?

atomic = no of protons.

mass number-atomic number = neutron number

the aurora is formed when charged particles emitted from the sun during a solar flare penetrate the earth's magnetic shield and collide with atoms and molecules in our atmosphere. these collisions result in countless little bursts of light, called photons, which make up the aurora.

auroras are generated by charged solar particles hitting molecules in earth's atmosphere. this usually happens in high latitudes, because our planet’s magnetic field tends to funnel these particles toward the poles. that’s why it can be experienced in northern ohio.
