Question

An electric dipole lies on the x-axis containing a charge of

-2.5 nC at x = -10.0 cm, and a +2.5 nC charge at x =+10.0 cm. Find the electric field 1 on the x-axis at the point (20.0 cm, 0) 2 on the y-axis at the point (0, 10.0 cm)

In the model of the hydrogen atom, the proton,(+e) and electron, (-e) (having charge =±e =±1.6X10^−19C) are separated by 5.29x10^-11m. Calculate the electric potential energy of this atom.

Suppose turbulent motions in thunderstorms cause charge separations that result in a potential difference of 50 MV between the cloud and the ground. When lightning occurs, it transfers 10 C of charge between the cloud and ground. How much energy is released in the lightning?
