The north-pole end of a bar magnet is held close to a stationary positively charged piece of plastic. Therefore, the plastic piece will be repelled as N-pole repels a positively charged object O the plastic piece will be attracted as N-pole is likely to attract a charged object regardless of what the charge is positive or negative. the plastic piece will be unaffected as it's a piece of nonmetal. O the plastic piece will be unaffected as magnetic force may be effective only on a moving charged object.
