Answer:
The discharging current is
Explanation:
From the question we are told that
The radius of each circular plates is R
The displacement current is
The radius of the central circular area is
The discharging current is mathematically represented as
where A is the area of each plate which is mathematically represented as
and k is central circular area which is mathematically represented as
So
substituting values
The work done is 200 J
Explanation:
The work done by a force applied to move an object is given by:
where
F is the magnitude of the force
d is the displacement of the object
is the angle between the direction of the force and of the displacement
In this problem, assuming that the force applied by the workers is parallel to the direction of motion of the crate, we have:
F = 10.0 N
d = 20.0 m
Therefore, the work done is:
