Question
if more air is pushed in soap bubble the pressure in it decreases WHY?
Joshi sir comment
since inside soap bubble pressure is given by the formula P0 + 4T/R and on pushing air R will increase so pressure will decrease.

As we know Pi = Po + 4T/R
when u will push air R will increase . 4T/R will decrease
Take 4T/R = x
intially Pi= Po + x
after pushing air 4T/R has decreased. let it has decreaed by k
now it has become Pi, = Po+x-k
Now compare which is greater Pi or Pi, obivously Pi
