<h3>Reducing Surface Area.</h3>
If the surface area becomes smaller, the pressure becomes larger.
I think it is because the electrons repel each other
Answer:
F = 19.1 N
Explanation:
To find the force exerted by the string on the block you use the following formula:
(1)
k: spring constant = 95.5 N/m
x: displacement of the block from its equilibrium position = 0.200 m
you replace the values of k and x in the equation (1):

Hence, the force exterted on the block is 19.1 N
