Which law describes the interactions between charged particles when they are not in contact?
2 answers:
Answer:
B) Coulomb's law
Explanation:
As per coulombs law if two point charges are placed at some distance from each other then the force of interaction between them is given as
here we know that
= two charges between which force of interaction is required
d = distance between two charges
Faraday law is used to find the induced EMF due to changing magnetic flux
Ohm's law is used to relate potential difference between the ends of a conductor with its resistance and its current

Answer:
It will not hit.
Explanation:
In this problem, we need to tell that was the cannonball able to hit its target of 50 meters when the initial velocity was 20 m/s.
When it will hit the target, final velocity, v = 0
Using third equation of motion as follows :
Here, a =-g
The target is in a straight line 50m away on the x-axis. As 50m is far from 20.40 m and that’s why it won’t hit.
