ANSWERS MUST BE CORRECT: (Detailed explanation of order of processes required. Take your time and answer it perfectly to receive credit. The most detailed answer and explanation will be awarded points).

An electrically neutral thin, square metal slab, measuring 6.00 cm on a side, is placed in a uniform external field that is perpendicular to its square area

Part A:

     If the top of the slab becomes negatively charged, what is the direction of the external field?

                          Downward or Upward?

Part B:

     What is the direction of the field that is generated by the charges induced on the slab?

                  Downward or Upward?

Part C:

    If the external field strength is 1330N/C , what is the strength of the field that is generated by the charges induced on the slab?

                           Eg = ???       N/C

Part D:

     What is the total charge on the negative side of the slab?

                           Q =     ???       pC

Explanation / Answer

part A. charge always flows from +ve terminal to -ve terminals

so here direction is upwards

part B. EF will be in the direction oc durrent so EF direction also upwards

partc. E = 1330 N/C

part D:

E = sigma/eo = 1330

sigma/ =Q /A = 1330 *8.85*10^-12 = 1.177*10^-8

Q = 1.177*10^-8 *0.06*0.06 = 4.23*10^-11 C
