PHYSICS HELP!!! Dipoles, and Electric Fields?
A certain electric dipole is placed in a uniform electric field E of magnitude 40 N/C. Figure 1 gives the magnitude t of the torque on the dipole versus the angle theta between field E and the dipole moment p. The vertical axis scale is set by t = 100 * 10^-28 Nm. What is the magnitude of p.
the figure 1 is an upside down parabola where the x-axis is theta and the y-axis is ts the graph maxes in the middle and passes through the origin.
Please show full solution. Thanks for your help!
The torque is simply T = Epsin(theta), thus p = T/(Esin(theta). If the scale also equals maximum T, then p = T/E = 2.5E-28 C-m.
