Obviously Lengthen... or
Explanation:
As we can observe from the equation, time period of a simple pendulum depends upon the length directly. When the gravitational acceleration increases the time period of the pendulum decreases and vice versa. So, by increasing the length, the time period can be adjusted...
Answer:
Explanation:
Given
mass of boy=36 kg
length of swing=3.5 m
Let T be the tension in the swing
At top point
where v=velocity needed to complete circular path
Th-resold velocity is given by
So apparent weight of boy will be zero at top when it travels with a velocity of
To get the velocity at bottom conserve energy at Top and bottom
At top
Energy at Bottom
Comparing two as energy is conserved
Apparent weight at bottom is given by
