The penguin has a sleek body that helps it to move quickly in water.
Given :
The distance between a point charge and a neutral atom and is multiplied by a factor of 5.
To Find :
By what factor does the force on the neutral atom by the point charge change.
Solution :
We know, electrostatic force between two object is directly proportional to product of charge and inversely proportional to distance between them.
Now, charge in neutral atom is 0 C.
So, the electrostatic force between two of them is also 0 N.
Therefore, by changing distance between the charge the forces did no change ( it remains zero).
Bohr's atomic model proposed that electrons move in specific orbits around the nucleus of an atom.
Answer: A boron atom has 2 electrons at the first energy level and 3 electrons at the second energy level.
