When a charged object polarizes another, why is there an attraction between the objects?

The reason that why there is an attraction between the objects.
Answer to Problem 21A
There is an attraction between the objects because the unlike charges are closer.
Explanation of Solution
Introduction:
Separation of opposite charges in an object is defined as polarization. Suppose all the positive charge gets separated on the left side of the object and the negative charge get separated on the right of the object. Hence the charged object can induce the movement of electrons.
When a charged object polarizes another object, then the like charge are away from each other and the unlike charges are closer. Hence, the force of attraction between the unlike charges is greater than the force of repulsion between the like charges. That is why there is an attraction between the objects.
Conclusion:
Thus, there is an attraction between the objects because the unlike charges are closer.

However, you notice when you put on your vertically polarized sunglasses, the light reflected off the lake no longer reaches your eyes. What is the angle between the unpolarized light and the surface of the water, in degrees, measured from the horizontal? You may assume the index of refraction of air is nair=1 and the index of refraction of water is nwater=1.33 . Round your answer to three significant figures. Just enter the number, nothing else.arrow_forward

The mass of each sphere is 0.09 kg. If the spheres are initially 0.10 m apart, how fast will the sphere be moving when they are 1.5 m apart?arrow_forwardpls help on allarrow_forwardpls help on thesearrow_forward

Mount Everest, Earth's highest mountain above sea level, has a peak of 8849 m above sea level. Assume that sea level defines the height of Earth's surface. (re = 6.38 × 106 m, ME = 5.98 × 1024 kg, G = 6.67 × 10 -11 Nm²/kg²) a. Calculate the strength of Earth's gravitational field at a point at the peak of Mount Everest. b. What is the ratio of the strength of Earth's gravitational field at a point 644416m below the surface of the Earth to a point at the top of Mount Everest? C.
