Right after S is moved to the position a, following a long time in the position

Question

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.

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

After S is in the position b for a long time, the current through R becomes close to 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 potential across C is nearly zero.

If S is in the position b for a long time, the current through R approaches /R.

Explanation / Answer

Right after S is moved to the position a, following a long time in the position b, the current through R is zero - True 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 - True If S is in the position a for a long time, the charge on C approaches zero - False After S is in the position b for a long time, the current through R becomes close to zero - True Right after S is moved to the position a, following a long time in the position b, the current through R is /R - False Right after S is moved to the position b, following a long time in the position a, the potential across C is nearly zero - False If S is in the position b for a long time, the current through R approaches /R - False
