Finding the Magnitude of a Horizontal Force

AI Thread Summary
To find the magnitude of the horizontal force on a 2.0 kg block on a 60-degree incline, resolve the horizontal force into two components: one along the incline and one perpendicular to it. The weight of the block also needs to be resolved into components, with one being mgcosθ (perpendicular) and the other being mgsinθ (along the incline). The normal force can be calculated using the equation Fn = mgcosθ. By identifying the directions of these forces, the required results can be determined. The discussion emphasizes the importance of breaking down forces into components to solve the problem effectively.

Homework Statement


A 2.0 kg block on an incline at a 60 degree angle is held in equilibrium by a horizontal force.
A) Determine the magnitude of this horizontal force (disregard friction)
B) Determine the magnitude of the normal force on the block.

I have no idea which equation to use. All the equations I can find don't give me enough information to start the problem. The only equations that I can find include friction and other things not present in the problem.

Hi GhostlyKiss, welcome to PF.
Resolve the horizontal force into two components. One along the inclined plane ant the other perpendicular to the inclined plane. Similarly resolve the weight of the block. From these you can get the required results.
 
How do I resolve the horizontal force? Is Fn=mgcos\oslash an equation I would use?

One component of mg is mgcosθ. What is the other component of mg along the inclined plane? Similarly find Fcosθ and Fsinθ. Identify their directions.
 
Ok thank you :)
 

Thread 'Errors and significant figures'

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

Figure 1 Overall Structure Diagram Figure 2: Top view of the piston when it is cylindrical A circular opening is created at a height of 5 meters above the water surface. Inside this opening is a sleeve-type piston with a cross-sectional area of 1 square meter. The piston is pulled to the right at a constant speed. The pulling force is（Figure 2）： F = ρshg = 1000 × 1 × 5 × 10 = 50,000 N. Figure 3: Modifying the structure to incorporate a fixed internal piston When I modify the piston...

Thread 'A cylinder connected to a hanging mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
