Answer:
(4)
more protons than electrons
Explanation:
Total positive change on the object is given as

now by the law of quantization of charge we know that the charge on any body is always in form of integral multiple of charge of an electron.
So we will have

here we know that


Now we know that the object is positively charged so here electrons must be less in numbers than protons
so correct answer will be
(4)
more protons than electrons
It would mean that only one side of earth would be light and the other dark all the time also we would only see the sun on one side and on the other we see the moon
Net force is the vector sum of forces acting on a particle or body. The net force is a single force that replaces the effect of the original forces on the particle's motion. It gives the particle the same acceleration as all those actual forces together as described by the Newton's second law of motion.
To solve this problem it is necessary to apply the conservation equations of the moment for an inelastic impact or collision. In turn, it is necessary to apply the equations related to the conservation of potential energy and kinetic energy.
Mathematically this definition can be expressed as

Where,
Initial velocity of each object
Mass of each object
Final velocity
Our values are given as

Replacing we can find the value of the final velocity, that is


From the definition of the equations of simple harmonic motion the potential energy of compression and equilibrium must be subject to

Since there is no kinetic energy due to the zero speed in compression, nor potential energy at the time of equilibrium at the end, we will have to

Re-arrange to find A



Finally, the period can be calculated through the relationship between the spring constant and the total mass, that is,



The ground is a foundation for many of the things of our lives. It is the foundation for the buildings in our life such as our houses, schools, work, hospital, and so on. It is the foundation for our lives that we often take for granted and it nurtured the trees and nature around us.
