Can an electron have 0 energy?
Conclusion: an electron can have energy zero if it is the electron at infinity from the nucleus of an atom, which now has become an ION.
What is the energy of an electron in n ∞ state?
The energy at n=infinity is called the ionization energy of the atom.
What will be the weight of a person on the Earth who weighs 9n on the moon?
Answer Expert Verified 54 newton . because moon gravity is 1/6 of earth gravity .
What is the gravitational potential energy at infinity?
The gravitational influence on a body at infinity is zero, therefore, potential energy is zero, which is called a reference point. Gravitational Potential Energy Formula The equation for gravitational potential energy is: ⇒ GPE = m⋅g⋅h
How do you calculate the gravitational potential energy on Earth?
Thus gravitational potential energy = Gravitational potential at a point x Mass of the body at that point. Where G is universal gravitation constant and M is the mass of the earth and r is the distance of the body from the centre of the earth. Conventionally gravitational potential energy on the surface of the earth is considered to be zero.
Why is the gravitational potential a negative quantity?
Where G is universal gravitation constant and M is the mass of the earth. As gravitational field intensity is zero at infinity and it goes on decreasing as the test mass approach the attracting body. Thus the body moves from higher potential to lower potential, hence gravitational potential is a negative quantity. It is maximum at infinity (zero).
Is gravitational potential a scalar or vector quantity?
As gravitational field intensity is zero at infinity and it goes on decreasing as the test mass approach the attracting body. Thus the body moves from higher potential to lower potential, hence gravitational potential is a negative quantity. It is maximum at infinity (zero). It is a scalar quantity.
