Question

on increasing the mass of a body suspended at the end of a spring kept vertically its period

Answer 1

hey there !!

◆ suppose a body of mass "m" is suspended by spring of spring constant 'k'
...|
...|
...|
...|
[ m ]

=) we know that weight 'mg' acting downward and spring elongates 'x' so spring force ' kx' developed which balances the weight .

=) so here , kx = mg ---------(1)

now again spring is displaced x' from mean position

now equivalent force is

=). F = -(k( x+x') - kx )

=) so F = - kx'

here this is condition S.H.M

for this particle executing S.H.M .

=) Time period (T) = 2π√m/k

so , here we can see that :
time period is directly proportional to mass ..on increasing mass time period also increases ...

Hope it will help u

Answer 2

Answer:

increases

because T is proportional to d
