A simple pendulum with point of suspension O oscillates freely between the points A and B. A peg is placed at some point C above the line AB but between the lines OA and OB. The string now bends at C and the bob will reach an extreme point D. Ignoring friction, where will the point lie?
Which option is right?
(A) On the line AB
(B) Above the line AB
(C) Below the line AB
(D) Co-incide with B
Dear student
As the point C lies between A and B .we can conclude from the information given in the question that it is forming a traingle AOB and point C lies somewhere in between the triangle .Now it is bending at the point C so its extremum must lie above the line AB.
Option B is correct.
