Answer:
For electric field inside cylinder, check image 02 attached
For electric field outside cylinder, check image 03 attached
Explanation:
Let's consider the polarized cylinder as superposition of two cylinders with opposite,equal, uniform charge densities in a way shown in the figure in the "image 01"d attached ;
In general, if we have an object with polarization (P¬) , then we have to take two objects with similar shape to the system, with opposite, equal, and uniform charge densities and then we super-impose these two objects in such a way that the total dipole moment of this superimposed system is equal to the total dipole moment of original system.
Now, we can take the super- imposed system as equivalent to the original system for calculating electric field and potential.
Therefore,
For the electric field inside the cylinder, check the solution in "image 02" i attached
For the electric field outside the cylinder, check, "image 03" i attached.
Answer:
Max. = 13 N
Mjn. = 3 N
Explanation:
Max. resultant will be when these forces are being applied in the same direction(along the same line), we'll simply sum up the forces to get the resultant in this case.
= 5 + 8
= 13 N
Min. resultant will be when these forces are being applied in opposite directions (the forces must be present along the same line).
We'll subtract them to get the resultant now
= 8 - 5
= 3 N
The correct answer is letter B. 13.7 millimeters. <span>An object is located 51 millimeters from a diverging lens. The object has a height of 13 millimeters and the image height is 3.5 millimeters.
</span>
mi / mo = hi / ho
mi / 51 = 3.5 /13
178.5 = 13 mi
mi = 13.7 mm
