before you say "The answers are in your text" I don't have one this is based on memory and guessing. Welcome to the 2017 school system.
1. Objects with like charges ___________ each other while opposite charges ______________ each other.
2. The direction of an electric field is always in the direction _______________ would naturally move.
3. A negatively charged object will move in the _____________ direction of an electric field.
No text? No notes?
a. repel, attract
b. a positive charge
c. opposite the
What is the name of your school?
No this is a worksheet and this is based on memory. Thank you bobpursley. I go to FLCA
1. Objects with like charges __repel__ each other while opposite charges __attract__ each other.
To understand why this is the case, we can refer to Coulomb's law. Coulomb's law states that the force between two charged objects is directly proportional to the product of their charges and inversely proportional to the square of the distance between them.
When two objects have like charges, they both have an excess of either positive or negative charges. Since charges of the same sign repel each other, the objects will experience a repulsive force, causing them to move away from each other.
On the other hand, when two objects have opposite charges, they have an excess of different charges. Charges of opposite sign attract each other, resulting in an attractive force between the objects. This attraction will cause the objects to move closer to each other.
2. The direction of an electric field is always in the direction __towards positive charges__.
To understand this concept, we need to consider the nature of electric fields. An electric field is a region around an electric charge where another charge experiences a force. The direction of the electric field is determined by the direction of the force that a positive test charge would experience when placed in that field.
Since positive charges repel each other, a positive test charge placed in an electric field will be pushed away from the source of the field. Therefore, the direction of the electric field is opposite to the direction in which positive charges would naturally move, which is towards the positive charges.
3. A negatively charged object will move in the __opposite__ direction of an electric field.
Similar to the previous explanation, a negatively charged object experiences an attractive force towards a positively charged object. Therefore, when placed in an electric field created by a positive charge, the negatively charged object will move in the opposite direction of the field, i.e., towards the positive charge.
This can be understood by considering that opposite charges attract each other. Since the electric field is directed towards positive charges, the negative charge is compelled to move in the opposite direction, following the attractive force.
