1I think it should be C . well there exists an internal field. whther it's in a circuit or not.
and for 2nd one is the field outwards or inwarsds?
1plz go thru this guys
this would help than me explaning

24sorrrrrrrrry...................misunderstood it as vertical.......
3i think u have cleared one of my doubt regarding the qn 3) abhi i dont know y u had ask this qn da.may be u r expecting more for dat qn.if so i dont know da
3for the first ques
statement 1 is false and statement 2 is true
statement 1 is false becos electrostatic field can be produced only by static charges in an open circuit no charge dat can flow and therefore no field due to the current and therefore the point charge will remain as it is
24i think for 2nd question power eqn will be::
mgv=dK/dt +dH/dt...................what do u say??
62last part..
let the charge distribution on each face of the capacitor be
Q, q, 12-q, 4-Q
Now the potential due to these charges will be ??
Have u tried a problem of finding the potential difference between two parallel plates with different charges? (Hint: Gauss' law!)
33Initially both the keys are open and given charges are given to plates...
when both keys are closed find final charge distribution..
those 10,4,8,-6 are charges in columb
