Gravity is the force that keeps us on the earth. it pulls us towards the center of the earth. if you were to move from the surface of the earth to a point higher up, away from the earth, what type of energy would be gained? a. chemical potential energy b. gravitational potential energy c. gravitational kinetic energy d. kinetic potential energy

Explanation:

The gravitational potential energy is the energy that a body or object possesses, due to its position in a gravitational field.

That is why this energy depends on the relative height of an object with respect to some point of reference and associated with the gravitational force.

In the case of the Earth, in which  the gravitational field is considered constant, the value of the gravitational potential energy will be:

Where is the mass of the object, the acceleration due gravity and the height of the object.

As we can see, the value of is directly proportional to the height.

two charges are fixed in place on the x-axis as shown. the charge at x = 0 is negative and has magnitude q = 2 μcoulombs (1 μcoulomb = 10-6 coulombs). the charge at x = d, (d = +12 cm), is positive and has magnitude q = 4 μcoulombs. find a point x = xo along the x-axis at which the electric field is zero.
