I have my Plus classes in the morning this is the reason my CNA goes late
ma'am can you explain the unification of electricity and magnetism by lorentz and maxwell
thank you sooooooo much mam !! plzzzz do magnetism course also!!!
Mam electrostatics chapter 2 ki video bna dijiye...plz
mam when silk and glass rod is rubbed then why silk gets -ve charge and rod get +ve charge . silk p -ve charge hi kyo aya

Because every material has different tendency to lose electrons when provided energy is any form. When silk is rubbed with class, energy is provided by friction to glass rod as well as silk. But since the ionisation potential is lesser for the glass, it loses electron more easily, thus acquiring a positive charge. It also explains why silk gets negative charge

ohhh😮 thank u for explaining i was really wondering how is happens. thank u so much🤗🤗
very nice mam....best....mam can u please make a video on electrostatics plzz...!!!
