Problem 3 please, the choices are true or false
Thanks!

Using the same data as above, consider the case when the switch is in position b for a long time, then switched to position a at time t = 0. What is V_c at time t = 2.0 milliseconds? Which of the following statements are correct for the RC circuit shown? Select true or false for each statement. (E is the emf of the battery.) Right after S is moved to the portion b, following a long time in the position a, the potential across C is nearly zero. If S is in the position a for a long time, the charge on C approaches zero. 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 zero. Right after S is moved to die position b, following a long time in the position a, the potential across C is close to E. Right after S is moved to the position b, following a long time in the position a, the current through R is E/R. The longer S is kept in the position a, the lower is the energy stored in C. An RC circuit, hooked up to a battery as shown in the figure below, starts with an uncharged capacitor.

Explanation / Answer

Problem 3 :

False : after long time in position "A" , the Capacitor gets fully charged and has the voltage equal to battery voltage. as the switch is moved to position "B" , the the capacitor is fully charged and has maximum Voltage across it.

False : after long time in position "A" , the Capacitor gets fully charged and has maximum charge across it.

False : Right after S is moved to B after long time at A, the Voltage across the capacitor is maximum and since the resistor is in parallel with the capacitor, the Voltage across resistor is maximum and has the maximum current in it .

True :

True : after long time in position "A" , the Capacitor gets fully charged and has the voltage equal to battery voltage. as the switch is moved to position "B" , the the capacitor is fully charged and has maximum Voltage across it equal to E .

True : Right after S is moved to B after long time at A, the Voltage across the capacitor is maximum and since the resistor is in parallel with the capacitor, the Voltage across resistor is maximum (E) and has the maximum current in it given as i = E/R

False :

the longer the switch is kep in position A , the more is the charge on capacitor , and since energy stored is directly propotional to square of charge stored, the more will be the energy stored
