Dependance of "g"

In ssc we have proved that "g" is not dependant on "m"..So why we write
F = mg
so,g = F/m

If you change $m$ then $F$ also changes proportionately and thus $g$ remains unchanged.

S.S.C এর বইতে এই প্রমান এর মধ্যে m কে ধ্রুবক ধরা হয়েছে। বইয়ে m ভরের কোন বস্তু ধরে প্রমানের শেষ পর্যন্ত একই বস্তু রেখেছে। m change করলে F change হবে। আমার এইটাই মনে হইতাছে।

@tanvirab. I understand you.you want to say that if we change m then F will change also. So, the value of g will unchange.....But dada ata korleo kintu g, m er upor dependant.From the equation (g=F/m) we can see that we shall get the value of g only when we shall put the value of m...so, g kintu after all m er upor depend korche..

Dipan, why don't you download avro. If you do not want to install avro/want to use it in cybercafe, you can download the portable edition, and use it from a pendrive. :)

No, $g$ does not depend on $m$. You do not need to know the values of $m$ to know $g$.
