Question

A spring of force constant k is cut into lengths of
ratio 1:2:3. They are connected in series and
the new force constant is k'. Then they are
connected in parallel and force constant is K'.
Then K: K' is
​

Answer 1

Answer:

k1=k k2=2k k3=3k use formula find ratio

Answer 2

1/11

See pic dear,

The formula for spring constants in series and parallel is just opposite to resistance

i.e.

in series

1/K = 1/k1 + 1/k2 + 1/k3

In parallel

K = k1 + k2 + k3
