A simple pendulum A and a homogeneous rod B hinged at its end
are released from horizontal position as shown in figure

AThe times period of swing of simple pendulum is greater than that
of rod if L = [IMAGE]BThe time period of swing of simple pendulum is equal to that of
rod if L = [IMAGE]CThe time period of swing of simple pendulum is greater than that
of rod if [IMAGE]DThe time period of swing of simple pendulum is equal to that of
rod if L[IMAGE]

Show answer and solution▾

from conservation of energy
for simple pendulum
[IMAGE] for homogeneous rod
[IMAGE] When [IMAGE] at all time
so time periods of swing are equal.
