Can someone explain to me, what is the difference between: PV=mRT and PV=nRT. and how to apply it? when to apply it? Thanks

In case of pv = mRT, R= characteristics gas constant (differnt for different gas,R=Ru/molecular mass) while in case of pv = nR u T, R u =universal gas contant(8.314 j/mol-k). Amar kumar...

As we know that F=qE also F=mg due to mass and gravitation there fore qE=mg q(v/d)=mg V=mgd/q now putting the values v=1.67*10-27*10*10-2/1.6*10-19 we get V=10-9 V hence the option (c) is...
