Answer:
Answer: 
 
The spring constant of the spring is 205.42 N/m. 
 
Explanation: 
 
Springs have their own natural "spring constants" that define how stiff they are. The letter k is used for the spring constant, and it has the units N/m. 
 
 k = -F/x 
 
The period of a spring-mass system is proportional to the square root of the mass and inversely proportional to the square root of the spring constant. 
 
Given: 
 
mass of object in SHM = m = 0.30 kg 
 
Time period of the spring mass system = 0.24s 
 
Spring constant = k ? 
 
Finding 'k' using Time period 'T': 
 
We know that
