That's the 'electrostatic' force.
The sun is the center of the solar system which is surrounded by the nine planets and they tend to orbit the sun in concentric circles with the sun as the center.
<h3>What is the solar system?</h3>
The term solar system has to do with the arrangement of the sun and the planets. The sun lies at the focus of the solar system. Now we know that there are nine planets that orbit around the sun. The distance between the planets and the sun depends on their relative proximity to each other.
Thus, the sun is the center of the solar system which is surrounded by the nine planets and they tend to orbit the sun in concentric circles with the sun as the center.

Answer:
0.087 m
Explanation:
Length of the rod, L = 1.5 m
Let the mass of the rod is m and d is the distance between the pivot point and the centre of mass.
time period, T = 3 s
the formula for the time period of the pendulum is given by
.... (1)
where, I is the moment of inertia of the rod about the pivot point and g is the acceleration due to gravity.
Moment of inertia of the rod about the centre of mass, Ic = mL²/12
By using the parallel axis theorem, the moment of inertia of the rod about the pivot is
I = Ic + md²
Substituting the values in equation (1)
12d² -26.84 d + 2.25 = 0
d = 2.15 m , 0.087 m
d cannot be more than L/2, so the value of d is 0.087 m.
Thus, the distance between the pivot and the centre of mass of the rod is 0.087 m.
Answer:
The atom becomes a positively charged ion.
Explanation:
- The building blocks of an atom are protons, neutrons, and electrons.
- The protons and neutrons present in the core of the atom are called nucleus.
- The electrons are scattered in an ordered way around the nucleus.
- The protons are positively charged and the electrons are negatively charged particles. The neutrons do not possess any charges.
- Binding energy is supplied to the atom to remove an electron.
- It is possible to remove the electrons of the lighter elements.
- When an electron is removed from the hydrogen atom. It becomes positively charged ion or simply proton.
- When all of the electrons are removed from the helium atom, it becomes a positively charged α particle.
- It is practically very difficult to remove all of the electrons from the heavier elements.
- When all of the electrons are removed from an atom it becomes an unstable positively charged ion.
