Question

Compare the time period of two simple
pendulums of mass 4kg and 16kg at a
place.​

Answer 1

Explanation:

kinetic energy is given by:

so taking velocity for mass 1kg as v

1

, we get

and taking velocity for mass 4kg as v1, we have

given that e

1

=e

2

,

equating the above terms and simplifying, we get,

now , momentum is given by,

let us assume ,p

1

as momentum for mass 1kg and p

2

for mass 4kg

so ,

p

1

=1×v

1

and p

2

=4×v

2

then,

p

2

p

1

=

4

1

=1:4
