The value is
Explanation:
From the question we are told that
The dielectric constant is k = 1.5
The area of each plate is
The distance between the plates is
The charge on the capacitor is
Generally the electric field in a vacuum is mathematically represented as
Generally is the voltage of the capacitor which is mathematically represented as
Here is the capacitance of the capacitor in a vacuum which is mathematically represented as
Here is a constant with value
=>
=>
So
So
=>
The electric field when the dielectric slab is inserted is mathematically represented as
=>
=>
Generally the electric field between the plates is mathematically evaluated as

Answer:
1) from the positive x-axis.
2)
Explanation:
Given:
speed of rowing in still water,
1)
speed of water stream,
we know that the direction of resultant of the two vectors is given by:
where:
the angle of resultant vector from the positive x-axis.
angle between the given vectors
When the rower wants to reach at the opposite end then:
so,
from the positive x-axis.
2)
Now the resultant velocity of rowing in the stream:
Therefore time taken to cross a 4 miles wide river:
