To find the force (F), we need to multiply the spring constant (k) by the elongation of the spring (l).

First, convert the length of the spring from centimeters to meters:
l = 4 cm = 0.04 m

Now we can calculate the force (F):
F = k l
F = 10 10^3 N/m * 0.04 m
F = 400 N

Therefore, the force exerted on the spring is 400 Newtons.
