dude first is easy sum conserve energy.thts the hint now start your problem with basics and certainly u vl end up with correct ans

Ans 2)6 kg
we find that when both ice and water are at 0°C still the water can supply 80000 cal of heat enough to melt 1000g(1kg) of ice to water.
so total amt of water finally at 0°C is (5+1)kg=6 kg

PLZ GIV IT A TRY SOM1

α=3 acc. to me

2 capacitors in parallel and one in series, u have to find v across the parallel one.

Q1...TAPAS...U RE RONG
Q2...6 IS DA ANS MANY OF US R GETTIN...BUT ANS GIVN 2

Potential of the 1st plate and the last plates are 0.

Now total charge on 3rd plate is 0. Let the charge on 4th plate and 1st plates be q' and q".

P.D of 1=0 implies q'=q3.

Similarly P.D of 4th plate is 0, so q" is found out....

Now see V₁-V₄=(V₁-v₂)+(V₂-V₃)+(V₃-V₄)=0....since both V₁=V₂=0.

Since net charge on V₃=0, we can get the middle term i.e. V₂-V₃.
Pls correct me if wrong.
