Very good video

NICE. Thank you

Beautiful explaination

Gluons are exchange particle in strong force but when neutron changes into proton the exchange particle are mesons (pions ) how? Are there two types of strong forces?

[@PhysicsMadeEasy]

Hi Zakir. The neutron transforming into a proton is by the weak force (a down becomes an up, and spits out a W- that then decays into electron and antineutrino)... the exchange particle is a W-... Mesons are composite particles made of quarks, these are not exchange particles.

[@PhysicsMadeEasy]

It's a typical beta decay btw...

[@zakirreshi6737]

@@PhysicsMadeEasy was talking about pn interaction...in meson theory exchange particle is pion

[@zakirreshi6737]

@@PhysicsMadeEasy i was taking about neutron gives proton +pion(+ive) and p gives n + pi+. Inside nucleus reactions which binds p-p, p-n, n-n by exchanging eachother...meson theory Not about the beta decays which is weak interaction n gives p+ e + antineutrino

@@zakirreshi6737 p --> n + PI+? where did you get this reaction from? First you would need quite some energy for this as a proton is lighter than a neutron (it's not natural), yet it could be possible at high temperatures enough. But it would be by the weak force via the exchange of a W+ boson. The Meson would come from the decay of the W+ boson into an up and and an anti down. The meson is just a final product of the reaction, not the exchange particle...
