Question 27 of 35 Map do Rank the changeied ollowing five situations described below, with greatest change at the top to least at the battom. Situation 1: a charge Q moving through a potential difference of Vc Situation 2: a charge 2Q moving through a potential difference of Ve Situation 3 a charge Q moving through a potential difference of Ve /2 Situation 4: a charge Q/2 moving through Greatest a potential difflerence of Ve/2 Least Situation 5: a charge 2Q moving through a Situation 3 Situation 5 Situation 2 Stuation 4 Situation 1 potential difference of 2V Previous ONext Save And Exit

Explanation / Answer

Change in electric potential energy is given by:

dU = q*dV

S1

dU1 = Q*Vc

S2

dU2 = 2Q*Vc = 2*(Q*Vc)

S3

dU3 = Q*(Vc/2) = 0.5*(Q*Vc)

S4

dU4 = (Q/2)*(Vc/2) = 0.25*(Q*Vc)

S5

dU5 = 2Q*2*Vc = 4*(Q*Vc)

From above values:

S5 > S2 > S1 > S3 > S4
