Unformatted text preview: We find the acceleration produced by the lectric field: m/s Because the field is constant, the acceleration is constant, so we find the distance from $ $ m (b)We find the time from $ s Problem G21.63. An electric dipole, of dipole moment % and moment of inertia & , is placed in a uniform electric field E. (a) if displaced by an angled as shown in Fig.21-43 and released, under what conditionss will it oscillate in simple harmonic motion? (b) what will be its frequency? Solution: a) for simple harmonic motion ' must be small, so that sin ( b) the period of a simple harmonic oscillator is ) & *, where * is the coefficient of proportionality in the relation between the * % sin ( % torque and the displacement angle: For a dipole, the torque is given as *% + ) % & Problem G21.71. Three charged particles are placed at the corners of an equilateral triangle of...
