Which of the following statements are correct for the RC cir

Which of the following statements are correct for the RC circuit shown? (Give ALL correct answers, e.g., BCD)

If S is in the position b for a long time, the charge on C approaches CE.

Right after S is moved to the position b, following a long time in the position a, the current through R is zero.

Right after S is moved to the position a, following a long time in the position b, the current through R is ?/R.

Right after S is moved to the position b, following a long time in the position a, the current through R is ?/R.

Right after S is moved to the position a, following a long time in the position b, the current through R is zero.

After S is moved to b, it takes a time ? = RC, for the charge on C to drop to 1/e of its initial value.

Right after S is moved to the position b, following a long time in the position a, the potential across C is nearly zero.

statements (C),(D),(F) are true because voltage across capacitor does not change instantaneously.
