A box of mass m is on a rough inclined plane that is at angle 𝜃 with the horizontal. A force of magnitude F at an angle φ with the plane is exerted on the block, as shown below. As the block moves up the plane, there is a frictional force between the box and the plane of magnitude f. What is the magnitude of the net force acting on the box? A) 𝐹𝑠𝑖𝑛𝜑−𝑚𝑔𝑐𝑜𝑠𝜃−𝑓 B) 𝐹𝑐𝑜𝑠(𝜑+ 𝜃)+𝑚𝑔𝑠𝑖𝑛𝜃−𝑓 C) 𝐹𝑐𝑜𝑠𝜑−𝑚𝑔𝑠𝑖𝑛𝜃−𝑓 D) 𝐹𝑐𝑜𝑠(𝜑+𝜃)−𝑚𝑔𝑠𝑖𝑛𝜃−𝑓 E) 𝐹−𝑚𝑔𝑠𝑖𝑛𝜃−𝑓 A 42.0 kg object is suspended by two cables attached to the ceiling and wall as shown below. What is the magnitude of the tension in cable attached to the wall? 160 N 224 N 291 N 335 N 440 N
