In the above image, what would the scale reading be? Let scale reading be $R$.
I was taught that the scale reading will always be the Normal force.
Thus imagining the compression of spring to be $x$ and the spring constant is $K$ I drew the free body diagram and got this:
Thus I conclude that the reading will show the total mass to be less than ($M_p+m_s$). Is this answer correct? Have I committed any error?
