Question

.Roshan applied a force of 144 N to the side of a cube-shaped wooden block to slide it away from himself . Assuming that he applied the force on the entire surface of the side of the cube , each side measuring 4cm , what was the magnitude of pressure applied on the said surface ?

Answer 1

• side of cube=4cm

Area=side^2=4^2=16cm^2=0.0016m^2

• Force=144N

$\\ \sf\longmapsto Pressure=\dfrac{Force}{Area}$

$\\ \sf\longmapsto Pressure=\dfrac{144}{0.0016}$

$\\ \sf\longmapsto Pressure=90000Pa$
