A) The net force acting on the block as given in the diagram is -40N
B) The net force acting on the block as given in the diagram is -25N
Force is defined as the pull or push that triggers a body to move from its initial position.
A) The force acting to the right of the box is along the positive x-axis while the force acting towards the left is along the negative-y axis.
[tex]\sum F_x= 20 - 60\\\sum F_x = -40N[/tex]
Hence the net force on the book is -40N
B) The forces acting on the body is along the y-component. Hence taking the sum of force along the vertical.
[tex]\sum F_y= 25 - 50\\\sum F_y = -25N[/tex]
Hence the net force acting on the block -25N
