19) the extension (E) of a spring
is directly proportional to
force (F) applied. When a force of 20N is applied the extension
is 1.8 cm. Find the extension
when the applied force is 15N
you need to find the force constant or the spring constant, you might know that F=Kx where F= load and x= extension, so by doing this you can find the constant(K),so 20/1.8= ans15/ans= 1.35 cm
