Answer:
Force between two equal charges will be 608.4 N
Explanation:
We have given charges 
Distance between the charges = 2.5 km = 2500 m
According to coulombs law force between two charges is given by
, here K is constant which value is 
So force 
"Four seismometer stations are the minimum needed to calculate the epicenter of an earthquake".
Answer: The above statement is False.
<u>Explanation:</u>
- Seismographs are devices used to measure the movement of earth and it uses a motion sensor named seismometers that are connected with a recording devices.
