The hypermetropia is a (a) short-sight defect (b) long-sight defect (c) bad vision due to old age (d) none of these Ans: (b) Solution: A person suffering from hyper metropia can see objects beyond a particular point called the near point. If the object lies at a point nearer than this point, then image is not formed at the retina. This is also known as long-sight defect.

A galvanometer acting as a voltmeter will have [2004, 2002] (a) a low resistance in series with its coil. (b) a high resistance in parallel with its coil (c) a high resistance in series with its coil (d) a low resistance in parallel with its coil Ans: (c) Solution: A galvanometer can be converted into a voltmeter by connecting the high ressistance in series with the galvanometer so that only a small amount of current passes through i
