# pls see the diagram  it is a quadrant of a circlea particle starting from ‘A’ goes to ‘B’ and a constant force acts at every instant in a direction towards ‘B’ . Find the work done by the force during this displacement? pls answer this . i need it immediately

$\\for that you need projection of \\displacement along that direction \\which is \sqrt{r^2+r^2}=\sqrt2r \\W=F.\sqrt2r$
