sir, in my physics class, my sir wrote the formula: µ1/d1 = µ2/d2pls explain the derivation of this formula and the formula itselfand pls tell me, is career point good for jee? should i go to kota for my preparation or stay in mumbai and prepare for jee?

Hi,

I would advise you to take a look on the formula from the book and try to understand it (It is difficult to write whole derivation here). Then, if you have any problem, post it to me.

Secondly, Kota is definitely a good option but you can do it while staying in mumbai (u would get good resources there too ).

thanks
