If the object has 2,750j, what is the height of the shelf the object is resting on?

Missing information:

The mass of the object is 15 kg.

18.7 m

Explanation:

The gravitational potential energy of an object is given by

where

m is the mass of the object

g is the acceleration of gravity

h is the heigth of the object, relative to the ground

In this problem, we know:

U = 2750 J is the potential energy of the object

m = 15 kg is the mass of the object

Solving for h, we find the height of the shelf:

The derivation of the field intensity in the dipole at the point of equatorial plane is the result of the horizontal line.

Explanation:

The equatorial line of an axis on dipole is define as the line is perpendicular at the axial line and to pass from the mid way between the charges at both the poles.

The result of this intensity is the vector sum of the intensities with the PA and PB. The line EA and The line EB can be resolved into horizontal and the vertical components.

The vertical components of dipole cancel to each other because they both equally or opposite directed.

The horizontal line up gives the result of the dipole at the point of the equatorial.
