Answer: Context Effect
Explanation:
<u>Context effect</u> refers to <u>the influence that external factors (the environment, for example) have on the perception of a stimulus</u>. This is a well-known aspect of cognitive psychology.
In fact, the situation stated in this question is a good example: It is not the same to observe the Moon with a naked eye and taking into account factors such as cloudiness, dust and whatever is surrounding this view that have effects on the observation; than observing this same Moon with a narrow tube in which our eyes focus only on the lunar surface, without taking into account the rest that surrounds that horizon.
To calculate the value of unknown charge, we use the formula the electric force between two charges
Here, q is unknown charge , , and
Now substituting the given values in above formula we get
or
The unknown charge is positive because the force between charges is attractive.
Net force is 5000 - 1000 = 4000 N
F = ma
4000 = 200a
a = 20 m/s^2
Your answer is 392.28 newtons on earth
C) The weight of the object on planet A will be less than the weight of the object on planet B.
This happened because: when gravitational pull of a planet is weak, an object will weigh less as a result of less gravity forcing it down to the ground.
