Answer:
<em>b. The force is 6 times the original</em>
Explanation:
<u>Coulomb's Law
</u>
The electrostatic force between two charged objects is directly proportional to the product of their charges and inversely proportional to the square of the distance between the two objects.
Written as a formula:
Where:
q1, q2 = the objects' charge
d= The distance between the objects
Suppose one of the charges is doubled, i.e., q1=2q1 and the other charge is tripled (q2'=3q2). The new force F' would be:
Operating:
Substituting the original value of the force:
b. The force is 6 times the original
The correct answer, is Option C, I hope this helps :)
Answer:
20kph
Explanation:
Since she travels 100kpm in 5 hours and 100 divided by 5 is 20 she would travel 20km in one hour
