You omitted some words in your question. How can you rest on a force?

This is a physics question. The math is trivial.

If 50 N is pushing the block, and the static friction coefficient is 0.45, a friction force of up to 0.45 M g = 88 N will tend to keep it in place. 50 N is not enough to move it.

In this case, the block will not move at all.
