One kind of e-book display consists of millions of very small spheres that float in a thin fluid layer between two conducting transparent plates. each sphere is black on one side and white on the other, and possesses an electric dipole moment directed from the white side to the black. When an electric field is applied between the plates, the spheres rotate so that their dipole moment lines up with the field. Depending on the fields direction, either the black or the white sides of th espheres can be made visible. The dipole moment of the spheres can be modeled as two opposite charges of magnitude 3.5 x 10^-15 C, separated by a distancce of 100 micrometers (um). What is the maximum possible torque on a sphere if the electric field between the transparent plates is 4.0 x 10^5 N/C

Explanation:

We are given that

Charge,q=

Distance, d=

Electric field,E=

We have to find the maximum possible torque on a sphere .

Electric dipole moment=qd

Using the formula

Electric dipole moment,p=

Maximum torque,

Using the formula

Torque,

Hence, the maximum torque,

gpe = mass x gravity constant x height or… gpe = mgh

where… mass: measured in kilograms (kg)

gravity: gravity constant on earth = 10.00 m/s2

height: measured in meters (m)

gpe: measured in joules (j) or kilojoules (kj)

how do you solve gpe?

gravitational potential energy (gpe) is the energy an object has because of its position above the. ground.

gpe = mass x gravity constant x height or… gpe = mgh.

given values:

mass = 0.3 kg.

jupiter is the largest planet in our solar system, having a mass and radius that are respectively, 318 and 11.2 times that of earth. suppose that an object falls from rest near the surface of each planet and that the acceleration due to gravity remains constant during the fall. each object falls the same distance before striking the ground. determine the ratio of the time of fall on jupiter to that on earth.
