I. igure is a map showing force lines and equal energy contours for a plane in a conservative field. The energy contours have units of J/kg. This means that the amount of energy transferred to/from the field as an object is moved depends on the mass of the object. This also means that the force acting on an object depends on the mass of the object. (a) If an object is moved from a position where its centre of mass...

Equipotential Lines The lines in the figure below show the equipotential contours in the plane of three point charges, Q1, Q2, and Q3. Note that these are point charges (one is not bigger in size than the others; they're points). That means that the potential goes to infinity as you approach them. We've cut off the contours at plus and minus 7kV. The white space is where the potential is greater or less than that. The values of the equipotential...

Sorry this problem has so many parts--thank you in advance for your effort. Conservative Forces It takes work to lift an object under the influence of the Earth's gravitational force. This increases the gravitational potential energy of the object. Lowering the ob- ject releases the gravitational potential energy that was stored when it was lifted. When you studied the gravitational force, you applied the term conservative to it because it allows the recovery of all of the stored energy. You...

3. (a) [6 pts.] Recall that gravitional force exerted on a mass m placed at (x, y, z) by a mass M placed on the origin is given by F = **** ř, where r = (x, y, z) is the position vector of mass m. A potential for this force field is given by f = 9 GMm .. “, i.e. Vf = Assuming M is the earth and GM ~ 4 x 1014 m's-2, use Fundamental Theorem of...
