Question

When the bob is displaced from the mean position P to a point A (called
extreme position) and released, we observe that the bob moves along the path
AP, crosses P and moves towards right along the path PB. It stops momentarily
at B (called an extreme position) and then retraces its path till P and repeats its
motion. If resistive forces are absent, the bob will remain oscillating between A
and B
(1) Where will be the speed of the bob zero
a) Extreme position
b) Mean Position
c) Nowhere on the path covered
d) at any position
(2) Where will be the energy of the bob maximum
a) At P
b) At A
c) At B
d) None of the above
(3) Mechanical energy will be constant at
a) At A
b) At B
c) At P
d) All the above
(4) Mention the energy transformation when the bob moves from
a) extreme to mean position
b) Mean to extreme position
c) Give two practical applications of a simple pendulum.​
