Explain the four fundamental forces with different examples

Answer» gaaand mara<br>Following are the four fundamental forces in nature:Gravitational force:\xa0Gravitational force is one of the four fundamental forces of nature. It is the weakest of the four. It is also the attractive force which arises from the gravitational interaction.Example:\xa0(i)\xa0The revolving of the moon around the earth is due to gravitational attraction between them.(ii)\xa0The formation of tides in the ocean is due to the gravitational force acting between the earth and the moon.Electromagnetic force:: It is the\xa0force between charged particles. Charges at rest have electric attraction (between unlike charges) and repulsion (between like charges). Charges in motion produce magnetic force. Together they are called Electromagnetic Force.Strong nuclear force:Strong Nuclear Force: It is the\xa0attractive force between protons and neutrons\xa0in a nucleus.It is charge-independent and acts equally between a proton and a proton, a neutron and a neutron, and a proton and a neutron. Recent discoveries show that protons and neutrons are built of elementary particles,\xa0quarks.Weak nuclear force: This force appears only in certain nuclear processes such as the\xa0β-decay of a nucleus. In β-decay, the nucleus emits an electron and an uncharged particle called\xa0neutrino.This particle was first predicted by Wolfgang Pauli in 1931.<br>Following are the four fundamental forces in nature:\tGravitational force:\xa0Gravitational force is one of the four fundamental forces of nature.
