Answer:
The spring constant is 215.6 N/m.
Explanation:
Given that,
Distance = 39 cm
Compresses length = 29 cm
Mass = 2.2 kg
We need to calculate the distance
Using formula of distance

Put the value into the formula
We need to calculate the spring constant
Using formula of restoring force


Where, F = force
x = distance
Put the value into the formula


Hence, The spring constant is 215.6 N/m.
Answer:
Negative electric charges
