A force that results from charged particles is called?
2 answers:
Answer:
Electrostatic force
Explanation:
The force that acts between charged particles is called electrostatic force. Its magnitude is given by:
where
k is the Coulomb's constant
q1 and q2 are the magnitudes of the two charges
r is the distance between the two charges
Concerning the direction of the force:
- The force is attractive when the two charges have opposite signs, and
- The force is repulsive when the two charges have same sign

Answer:
5 hours
Explanation:
Let the required time be x hours. The time will be the same for both cars.
The cars will cover different distances because they are travelling at different speeds.
<em>D=S×T </em>
The distance travelled by the slower car = 50×x miles.
The distance travelled by the faster car = 58×x miles.
The two distances differ by 40 miles.
58x−50x=40
8x=40
x=5 hours
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
A second method:
The difference in the distances is 40 miles
The difference in the speeds is #8mph.
The time to make up the 40 miles= =5 hours
