It's not the potential energy. It's just the potential.
It's greatest at the positive terminal of the battery or power supply.
To solve this problem we will apply the concepts of energy conservation and Newton's second law that defines force as the product of the object's mass with its acceleration. Additionally we will apply concepts related to the kinematics equations of linear motion.
For conservation of energy we have that work is equal to kinetic energy therefore,
Here,
F = Force
d = Displacement
m = Mass
v= Velocity
At the same time we have the relation of
Therefore the value of the force can be interpreted as the rate of increase in energy per unit of distance, which makes it equivalent to
Applying Newton's Second Law
In 4 seconds final velocity of the object becomes
Then the work done is equal to,
Then the displacement is,
Therefore the distance moved is 16m
Answer:
Downwards into the plane
Explanation:
Solution:-
- This is a conceptual application of hand rule. We will place our palm fingers open vertical to a plane surface. Then curl our fingers in and naturally point the thumb.
- The direction of curl of fingers denotes the direction of of current flow in the coil. Which in our case is "clockwise direction". We will orient/invert our right hand palm in such a way that we curl our fingers in clockwise fashion. Then stick the thumb out to give us the direction of magnetic field or North pole end. In our case the the thumb points downwards into the plane denoting that the magnetic field within the loop is also acting downwards into the plane.
- The bar magnet would be placed in such a way that North pole is pointing downward into the plane in the direction of magnetic field and end up at south pole pointing up out of the plane.
