6. [1pt]
Consider two separate systems, each with four charges of magnitude q arranged in a square of length L as shown above. Points a and c are in the center of their squares while points b and d are half way between the lower two charges. (For each statement select T True, F False).
A) The electric field at d is zero.
B) The electric field at b is zero.
C) The electric potential at b is zero.
D) The electric potential at d is zero.
E) The electric potential at a is zero.
F) The electric field at a is zero.
G) The electric potential at c is zero.
H) The electric field at c is zero.
Explanation / Answer
A) F The electric field at d is zero. FALSE because electric field by -q and -q do not cancel
B) F The electric field at b is zero. FALSE because electirc filed due to any pair do not cancel
C) T The electric potential at b is zero.TRUE because electric potential due to - q and +q cancel away
D) F The electric potential at d is zero. FALSE because -q and + q have different distance so do not cancel away
E) T The electric potential at a is zero.TRUE because electric potential due to - q and +q cancel away
F) T The electric field at a is zero. TRUE because electric field due to +q and -q cancel away
G)T The electric potential at c is zero.TRUE because electric potential due to - q and +q cancel away
H) F The electric field at c is zero. FALSE because electric field by -q and -q do not cancel
