There are three kinds of forces within the atom:

  i) Electromagnetic force of attraction between the electrons and protons

  ii) Electromagnetic force of repulsion between the protons or weak nuclear force

  iii) Strong nuclear force between the electrons and protons

<h3>What is nuclear force?</h3>

The electromagnetic force of attraction:

  • Electrons circle in the orbits above the nucleus. There exists an electromagnetic force of pull between the electrons and protons. That’s why electrons do not depart the atom.

Weak nuclear force:

  • It is an electromagnetic significance of revulsion between the protons in the nucleus of the atoms.

Strong nuclear force:

  • This force is strongest from all the fundamental details and exists between the protons and neutrons in the nucleus of an atom. This pressure overcomes the weak nuclear force and does not allow protons to stray out.

A force that varies with time is applied to an object. The force increases linearly from zero to twenty-four newtons during the
harkovskaia [24]

Answer:

144Ns

Explanation:

Impulse is the product of force and change in time or a measure of the change in momentum. Mathematically, Impulse is given as

J = FΔt

Where

J = Impulse,

F = Force,

Δt = change in time.

Due to the varying force, we know that the impulse varies at different points in the motion. Hence, the Net Impulse will be the addition of the individual impulses, i.e.

J = ΣJᵢ

J = J₁ + J₂ + J₃

J = F₁Δt₁ + F₂Δt₂ + F₃Δt₃

=> J = (24*2) + (24*4) + (0*2)

J = 48 + 96 + 0

J = 144 Ns

Calculate the relativistic speed of a particle at a time 6 s after it star t = 0 s . The mass of the particle is 6 × 10-2 kg and
Mars2501 [29]

Answer:

The relativistic speed of a particle is 0.0333\times10^{-5}c

Explanation:

Given that,

Time = 6 sec

Force = 1

Mass of the particle m=6\times10^{-2}\ kg

We need to calculate the acceleration

Using formula of acceleration

a = \dfrac{F}{m}

Put the value into the formula

a=\dfrac{1}{6\times10^{-2}}

a=16.67\ m/s^2

We need to calculate the velocity after 6 sec

Using equation of motion

v = u+at

Put the value

v=0+16.67\times6

v=100\ m/s

The velocity in term of c

v=\dfrac{100c}{3\times10^{8}}

v=3.333\times10^{-7}c

v=0.0333\times10^{-5}c

Hence, The relativistic speed of a particle is 0.0333\times10^{-5}c
