When the velocity is increasing the acceleration increases too
Sadly, no. The statement kind of has some appropriate words in it, but it's badly corrupted. Objects don't fall to Earth at a rate of 9.8 m/s, and the force that accelerates them downward is not a centripetal one.
Explanation:
The electric force between charges is given by the formula as follows :
k is electrostatic constant
r is distance between charges
Here, charges are equal and opposite. So,
It is clear the force is inversely proportional to the distance between charges and directly proportional to the product of charges. So, greatest force will be providing by :
- Increasing the magnitude of charges
- Decreasing the distance between charges.
The correct answer is:
<span>A. electron attraction between electron and nucleus = centripetal force of the orbiting electron
In fact, Bohr model depicts the atom as a nucleus surrounded by electrons in circular orbit around it, similar to the planets around the Sun. The centripetal force that keeps the electrons in circular motion around the nucles is provided by the electrostatic force between the electrons and the nucleus, so option A is the correct one.</span>
Mass is that quantity that is solely dependent upon the inertia of an object. The more inertia that an object has, the more mass that it ha
