The following information applies to the next two questions.
In the figure, a dipole with dipole moment p is shown as well as a point labeled B, which is located 10 units to the right of the center of the dipole. Now, assume a point charge is placed somewhere along the two dashed lines through B such that the electric field is equal to zero at point B. The point charge is positive and has the same magnitude as the dipole's charge.
Where should the point charge be placed relative to point B?
A) Left
B) Right
C) Above
D) Below
E) None of the above
How far should the point charge be from point B?
A) 10s
B) 10√5
C) 10/5
D) 103/2
E) 100s
Four identical electric dipoles are placed in a uniform electric field as shown below. Which dipole experiences the greatest torque?
