Question

A body of mass 100 gm is suspended from a spring of force constant 50 N/m. The maximum acceleration produced in the spring is:

• A. g/2
• B. g
• C. g/3
• D. g/4

Answer 1

Answer: (B)

To calculate maximum acceleration consider spring at the equilibrium position:
$F=ma$
where $F$ is force on spring which will be equal to $mg$ only (as gravity is the only force present.
Therefore, $ma=mg$ or $a=g$.
