Explanation:
The given data is as follows.
Electric field between plates without dielectric,
Electric field between the plates with dielectric, .
Permittivity of free space, =
Now, we will determine the charge density as follows.
=
=
Thus, we can conclude that the charge density on each surface of the dielectric is .
Since the direction of the needle depends on the proximity of the magnet thus this test alone is insufficient to determine the stronger magnet.
<h3>What is a magnetic field?</h3>
A magnetic field refers to the region where the effect of a magnet is felt. The magnetic field can be observed by the use of a compass.
Now, we know that the closer the magnet is to the compass, the greater the deflection hence this test alone is insufficient to determine the stronger magnet.

Answer:
Volume = 24 cm^3
Explanation:
We recall that the volume of the box is calculated via the formula:
Volume = length * height * width
and that in a product, the number of significant figures for the result should coincide with the number of significant figures of the factor that has the least of them.
In this case, all measures have the same number of significant figures: two. so we calculate the product, and then limit the answer value to exactly two significant figures:
Volume = 4.1 cm * 2.8 cm * 2.1 cm = 24.108 cm^3, which must be rounded to two significant figures as: 24 cm^3
