The energy that generates wind comes from what source?

The plum pudding model of the atom state that ?

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.)

Is there a point between a 10 nc charge and a 20 nc charge at which the electric field is zero?
