Question

$\large{\underline{\mathrm{\red{Question-}}}}$

Write about the properties of fundamental forces which exist in nature:

1). Strong nuclear forces
2). Electromagnetic force

$\rule{200}2$

Answer 1

AnswEr:

$\large{\underline{\sf{\pink{Strong\:nuclear\:force-}}}}$

• This force is the strongest force in nature.

• It is about 100 times stronger than electrostatic force.

• These are having short range ( about $\green{\sf{10^{-15}}$

• These are having independent charge.

• These are non central as well as non conservative one.

• This force don't obey inverse square law.

• Mediating particle $\longrightarrow$ π - meson

• These are basically attractive in nature.

$\large{\underline{\sf{\blue{Electromagnetic\:force-}}}}$

• This force is governed by coulomb's law.

$\large{\boxed{\red{\sf{F\:=\:\dfrac{kq_{1} q_{2}}{r^2}}}}}$

• It can be attractive or repulsive.

• These are Central and conservative forces.

• This force obey inverse square law.

• Their mediating particle is photon.

• Their range is infinity (∞}.

Answer 2

$\displaystyle{\mathfrak{Question:-}}$

Write about the properties of fundamental forces which exist in nature:

1) Strong nuclear forces

2) Electromagnetic force

$\displaystyle{\mathfrak{Answer:-}}$

1)

• Strong nuclear forces or interactions are the strongest of the four fundamental forces.

• It is million and million times stronger than gravitational force.
• When the particles are the farthest from each other, that time, it is the strongest.
• The closer the particles are, the weaker the force is.
• The distance between them is within $10^1^5$ (1 fm) metres.
• Strong nuclear forces are responsible for holding the nuclei of atoms together.
• This is the force that allows nucleus is held together in the atom.
• They are charge independent.

2)

• These have a long range and the effect of their forces diminishes over distance due to shielding effect.
• The range is infinity.
• They are considered as strong forces but still weaker than strong nuclear forces(nearly 100 times weak).
• It acts between charged particles, like negatively charged electrons and positively charged protons.
• Greater the charge is, greater is the force.
• It has two parts : electric force and magnetic force.
• The particles create a magnetic field around them as they move.
• This force obeys inverse square law(The intensity of light is inversely proportional to the square of the distance. This means that as the distance from a light source increases, the intensity of light is equal to a value multiplied by  $\bold{\frac{1}{d^2} }$).
