... Show that the same formula can be derived by finding the total amount of work which must be done to assemble the sphere of charge. Hint: Consider an intermediate stage at which a sphere of radius r (< R) has already been assembled. Find the work done in adding a thin shell to it, and integrate the r ...

... 1. (20 pts) Simple capacitors (Jackson 1.6). A simple capacitor is a device formed by two insulated conductors adjacent to each other. If equal and opposite charges are placed on the conductors, there will be a certain difference of potential between them. The ratio of the magnitude of the charge on ...

... Newton's First Law: Newton's First Law states that a body of mass in a state of rest tends to remain at rest and a body or mass in motion tends to remain in motion, unless acted upon by another force.

... A potential difference of one volt means that it takes one joule of energy to move a one Coulomb charge in the field. A potential difference of 1000 V means that it would take 1000 J to move 1 C of charge in the field. Potential difference is also called electric potential or voltage. Potential diff ...
