Which objects can be electrically polarized?
a. negatively charged object
b. positively charged objects
c. neutral objects
d. both positive and negatively charge object

The correct answer is "c = neutral objects"

Explanation:

Hello!

Let's solve this!

An object is polarized when it has the same number of electrons as protons. That object is called neutral. When it has excess electrons, it has a negative charge. If you have excess protons, you have a positive charge.

The correct answer is "c = neutral objects"

weight of the box is given as

here this is placed on the inclined of angle 42 degree

now this weight will have two components one is along the incline other is perpendicular to it

so here we need to apply a force parallel to incline opposite to its component of weight

so here the component of weight is given as

here we have

so it requires 75 n force to move it upwards
