Let's analyze the situation presented
* A rod with positive approaches and the sphere is attracted, so the charge on the sphere is negative
* A rod with a negative charge approaches and the sphere is attracted, therefore the charge of the sphere must be positive.
For this to happen, the sphere must be unloaded and the charge that creates the phenomenon are induced charges because the mobile charges of the same sign as the sphere are repelled.

The distance from the vertical beam that the lower end of the support beam be placed along the horizontal floor is 3.00 m
<h3>Angle of elevation</h3>
The angle of elevation is the angle to which the eye must be raised in order to see an elevated obect at a height.
Now, we know that a right angle triangle is formed; we can obtain the distance from the vertical beam that the lower end of the support beam be placed along the horizontal floor from;
tan 28 = 1.6/x
x = 1.6 /tan 28
x = 3.0 meters
