PLEASE ANSWER MY 2 QUESTIONS IN SCIENCE THANKS
3.when a negatively charged object moves in the opposite direction of an electric force field,the potential energy of the object.
A.becomes zero(I PICK THIS)
B.increases
C.decreases
D.stays the same
4.the two south pole ends of two magnets are touching.Which of the following can be concluded?
A.no work was requried by an outside force.
B.the magnets are naturally attracted to each other.(I PICK THIS)
C.work was required by an outside force.
D.the potential energy of the magnets is low.
3. B
4. C
Anonymous is wrong on NO. 3, the real answer is C for number 3, so Number 3 and 4 are both C
To answer question 3, the negatively charged object is moving in the opposite direction of the electric force field. The potential energy of an object in an electric field is given by the equation: potential energy = electric charge x electric potential.
In this scenario, the negatively charged object is moving opposite to the electric force field, which means it is moving in the direction of decreasing electric potential. As the object moves towards regions of lower electric potential, its potential energy decreases. Therefore, the correct answer to question 3 is C. The potential energy of the object decreases.
To answer question 4, when the two south pole ends of two magnets are touching, they naturally repel each other. This means that work is required by an outside force to bring the magnets together against their natural tendency to repel. Therefore, the correct answer to question 4 is C. Work was required by an outside force.
It's important to note that these answers are based on the principles of electromagnetism and the behavior of magnets in a magnetic field.
