instead of a rightward electric field 
.
A. Clockwise, to align itself with the field.
B. Counter clockwise, to align itself with the field.
C. 180° either clockwise or counter clockwise.
D. It won’t turn, as it is already aligned with the field.
E. It won’t turn, because the field wants to twist it around a different axis altogether.
F. It won’t turn because it is not affected by this field.
B. Counter clockwise, to align itself with the field.
