(a) 3000 V
For two parallel conducting plates, the potential difference between the plates is given by:
where
E is the magnitude of the electric field
d is the separation between the plates
Here we have:
is the electric field
d = 4.00 cm = 0.04 m is the distance between the plates
Substituting,
(b) 750 V
The potential difference between the two plates A and B is
Let's take plate A as the plate at 0 volts:
The potential increases linearly going from plate A (0 V) to plate B (3000 V).
So, if the potential difference between A and B, separated by 4 cm, is 3000 V, then the potential difference between A and a point located at 1 cm from A is given by the proportion:
and solving for V(1 cm) we find:
Answer: More work will be done in case A
Explanation:
Work is said to be done when a force applied to an object causes the object to move through a distance or height.
Work = Force × distance
If the heavy load is pulled straight up with a massless rope, then the object is pulled through a height at an angle perpendicular to the ground (i.e 90°)
Much work will be done in case A and less work in case B. Less work is done in case B due to the use of a machine which is an inclined plane. The use of machine makes work much easier and it allows us to do work in a more convenient manner. It allow us to overcome a much larger load using minimal effort. For the first case, much work will be done since we are carrying through a vertical height which requires more effort compare to when an inclined plane is used.
Also note that the higher the angle of inclination, the more the work done on the object and vice versa
Answer:
ACCELARATION
The slope of a velocity graph represents the acceleration of the object. So, the value of the slope at a particular time represents the acceleration of the object at that instant.
