Which energy is maximum at extreme position?a)K.E.b)P.E.

b)P.ESINCE AT EXTREME POSITION VELOCITY BECOMES ZERO SO, K.E IS ZERO SO,P.E IS MAXIMUM .At mean position K.E is maximum since velocity is maxmium at mean position and then decrease while moving towards the extreme position .And then at extreme position velocity becomes zero and hence, K.E becomes zero and P.E is maximum and equal to M×G×(DISTANCE COVERED BY THE BOB FROM MEAN POSITION TO EXTREM POSITION).....
