School starts on tuesday, and i have no idea what to anyone have any ideas? .

When a neutral charge, comes into contact with a positive charge they repel each other nothing happens the neutral charge becomes negative they attract each other

Charge is distributed along the entire x-axis with uniform density λ. how much work does the electric field of this charge distribution do on an electron that moves along the y-axis from y = a to y = b? (use the following as necessary: a, b, ε0, λ, and q for the charge on an electron.)

Scientific models are based on current knowledge, which can limit their effectiveness when new discoveries are made.
