@ rohit
your questions are not clear also the image , kindly upload a clear image without that uc browser tagup .
thats blocking the question as well as its figure .
but , as per my understanding , i am giving the correct approach toi this question .
1- the space in between the plate will have the same electric field which was there before the dieletric.
apply this concept to solve the frst bit of this question .
for the 2nd bit
consider the empty space of capacitor also a capacitor,apply series combination .
you have two air capacitor and a dielectric capacitor.
apply series combi to to find net Capacitance .
HOPE IT CLEARS YOUR QUERY
IF NOT THEN POST A DIFFRENT QUESTION WITH CLEAR IMAGE
ALL THE BEST ..
