I think this belongs in the homework section.

Anyway, some help to help you help yourself:
1) Your voltage is DC, i assume.
2) A capacitor is an infinite resistor for DC (at least in theory).
3) An inductor is a short circuit for DC (in theory, too).
4) A resistor behaves according to Ohm's law.

These are the building bricks to analyze the circuits you've shown us.

Regards,
Harald

1. There are two answers since you have two resistors.
Find the total resistance.
Calculate the current using Ohms law.
Calculate the voltage across each resistance using Ohms law.

2. How much resistance will an ideal inductor have? (It is all at DC)

3. How much current will pass through a capacitor at DC?

when capacitor is in infinite resistor means looks like open ckt , so no current will flow through it, am i right.

You are right.
When no current flows through the resistor, what is the voltage across it?

Once the capacitor is charged, the current flow is 0 A.
Puzzle: When 0 A flow through the resistor, what is the voltage across the resistor?

The rest of the voltage must drop across the capacitor.
