An electric dipole with a dipole moment is inserted in a uniform electric field 35- as in Figure. Due to the torque on the dipole applied by the electric field, the dipole rotates around an axis O perpendicular the plane of the field. Which of the followings is/are true about the dipole? I) Its moment of inertia around the rotation axis is constant. II) Its angular acceleration is constant during the rotation as the magnitudes of and are constant. III) The magnitude of the torque is constant during the rotation as the magnitudes of and are constant.

Je zstand thing shar Spring Consider the electric dipole shown in the figure. If the charges each have a magnitude of 25 nC, are separated by 6.17 mm, and the external electric field has magnitude E = 50 N/C, calculate the torque n (in N.nm) on the dipole when 0 = 17°. Let of the paper" be the direction of positive torque. "out N.nm
