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.2143 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...
