Answer 1

Answer:

Correct option is

B

π

k

m

+π

k/2

m

The situation oscillate down to up as a two spring connected and from up to down as a single spring-mass connected

i)T

1

=π

k

m

ii)k

eq

=

k+k

k.k

=

2

k

Now T

2

=π

k/2

m

Total time period T=T

1

+T

2

T=π

k

m

+π

k/2

m
