for part a) we have formula
C=Q/V=Q/Ed
so when we insert a dielectric ,electric field decreases because there is a capacitor
and this increases the capacitance and since capacitance is inversely proportional to V so V will decrease.
a) true
b) we have
C=Q/V=Q/Ed
with decrease in d capacitance increases
and U=1/2CV2
and C increases so energy increases
b) true
c) C=Q/Ed
with decrease in d , C increases as both of them are inversely proportional
c) false
d) again when we insert a dielectric the electric field decreases because there is a capacitor due to which the capacitance increases
as C=q/Ed
and we have U=1/2CV2
since u and c are directly proportional , so an increase in C will increase U
d) true
e) we have C=Q/Ed
with increase in d , C decreases
and C=Q/V
so decrease in C increases V
e)true
f) in presence of a capacitor the electric field decreases which increases capacitance
as C=Q/Ed
so answer
f) true.
