Answer:
Force, F = −229.72 N
Explanation:
Given that,
First charge particle,
Second charged particle,
Distance between charges, d = 0.0359 m
The electric force between the two charged particles is given by :
F = −229.72 N
So, the magnitude of force that one particle exerts on the other is 229.72 N. Hence, this is the required solution.
Answer:
<em>Correct answer: B.</em>
Explanation:
Electrostatic Field
It measures the electric effect of a charge distribution in its surroundings. If we wanted to test or measure the electric field by using a point-charge of value q', then the electric field is
The electrostatic force between two point charges is
So, the electric field is
The theory shows that the electric field doesn't depend on the test charge used, i.e., if we now use q'=-q', the electric force will be of the same magnitude but in the opposite direction, thus the electric field will be the same. Let's recall the formula is used to compute the scalar value of the field, the direction must be studied separately.
Now, if we changed the test charge to another value, say 2q, the measured force will be
And the new electric field is
We can see the electric field is not affected by the value of the test charge.
Finally, if we move the test charge to another location and keep the same charge, the electric force will vary and the electric field will be different.
Correct answer: B.
The conversion factor needed to change from kilometers to meters is
D) 1000
Explanation:
The meter (m) is the SI units to measure distance.
The kilometer (km) is a sub-unit, where the prefix 'kilo' stands for , or 1000. This means that:
Therefore, if we have a length expressed in kilometers, we just need to multiply by 1000 to get the corresponding length in meters.
For instance, if we have a length of
L = 3.47 km
To convert in meters, we do:
