Answer: 1. The field energy will increase
2. The energy increases, and the lines of force are denser
3. It points toward the field of earths magnetic poles
4. 1 and 2 only
5. 2, 4, 1, 3
Explanation: just took it
Neither set of choices is correct.
If the distance is tripled, then the forces decrease to
1/9 Fg. and. 1/9 Fe.
Note. When the objects are charged, the gravitational force Fg can almost always be ignored, since Fe is like 10^40 greater when the quantities of mass and charge are similar.
Gravitational potential energy<span> is </span>energy<span> an object possesses because of its position in a </span>gravitational<span> field. The most common use of </span>gravitational potential energy<span> is for an object near the surface of the Earth where the </span>gravitational<span> acceleration can be assumed to be constant at about 9.8 m/s</span>2<span>.</span>
The basic relationship between wavelength

, frequency f and speed c of an electromagnetic wave is

where c is the speed of light. Substituting numbers, we find:
