161- According to the figure below, a horizontal force $F$ is applied to a body. What is the minimum value of $F$ (in terms of the body's weight) so that the body remains stationary on the inclined surface? ($\sin 53^\circ = 0.8$, $g = 10\dfrac{m}{s^2}$) [Figure: A block of mass $m$ on an inclined plane at $53^\circ$ with a horizontal force $F$ applied, $\mu_s = 1$] (1) $\dfrac{1}{2}$ (2) $\dfrac{3}{5}$ (3) $\dfrac{4}{5}$ (4) $1$
