A certain electric dipole is placed in a uniform electric field E of magnitude 40 N/C. Figure gives the magnitude τ of the torque on the dipole not versus the angle θ between field E and the dipole moment p. The vertical axis scale is set by τs = 100 x 10-28 N ?? m. What is the magnitude of p?

(10-2 N- m)
