Answer:
As a positively charged object moves toward another positively charged object, their potential energy increases. True
As a negatively charged object moves toward another negatively charged object, their potential energy increases True
Explanation:
When two like charges move towards each other, there is increase in potential energy because the motion is in opposition to the direction if the field. Hence when two negative or two positive charges move towards each other, there is an increase in potential energy.
However, potential energy is inversely related to the distance of separation of the charges.
Answer:
Explanation:
As we know that diameter of hand crank is given as
Also the diameter of the shaft on which the rope is wound is given as
now we know that both are moving with same angular speed
so we will have
so we will have
Answer:
B it decreases
Explanation:
the movement of a positive test charge in the direction of an electric field would be like a mass falling downward within Earth's gravitational field. Both movements would be like going with nature and would occur without the need of work by an external force. This motion would result in the loss of potential energy
