Answer:
The answer is 4200 J.
Explanation:
The formula of work done is, W = F×D where F is the force of an object and D is the distance. Then you just substitute the values into the equation :
W = F×D
F = 42N
D = 100m
W = 42 × 100
= 4200 J
This question is an illustration of the distance postulate.
<h3>What is distance postulate ?</h3>
The distance between any two different points equates to a single positive real integer, according to the postulate of distance.
The full text is: The distance is a positive unique integer between every pair of different locations.
Consider two separate points A and B as an example.
The distance between A and B is the integer that represents the size of A and B.
The positive number (i.e. the distance) between A and B would be:
d= B-A
d = 6 - 1
d = 1

The glowing beam was repelled by a negatively charged plate because they were negatively charged
<h3>What are the nature of charges?</h3>
The nature of charges refers to the properties of charges.
There are two types of charges:
- negative charges
- positive charges
The law of electricity states that opposite charges attract whereas like charges repel.
Therefor, in Thomson’s experiment, the glowing beam was repelled by a negatively charged plate because they were negatively charged
In conclusion, like charges repel while opposite charges attract.
