Question

For the arrangement shown in the figure. The extension in the spring, for the block remains at rest is (g=10 meter per second square)

Answer 1

From Your FBD I Can Say That...

Here F = 100 N... How?

Only one force is acting on it and that is Weight Force..

So F = mg

F = 10*10 [Mass is 10 and G = 10]

F = 100

Now by using Formula

F = kx

100/1000 = x

x = 1/10 or 0.1
