Answer:
The theoretical angular magnification lies within the angular magnification range
Explanation:
From the question we are told that
The focal length of B is
The focal length of A is
The theoretical angular magnification is mathematically represented as
Form the question the measured angular magnification ranges from 4 -5
So from the value calculated and the value given we can deduce that the theoretical angular magnification lies within the angular magnification range
The general equation for voltage, field strength and distance is
<u>Explanation:</u>
Electric field is the measure of potential crossing per unit distance. In other terms we can say it as the work done to displace the charge from infinity to a point and the potential difference between them. The unit of Electric field is written as V/m, it is also known as field strength.
So the field strength is directly proportional to the potential and inversely proportional to the displacement or the distance covered by the charge. Thus, is the general equation relating voltage, field strength and distance.
