Homework Help Overview

The problem involves a 10 kg block at rest on a frictionless surface, connected by a light inelastic string to a rigid wall. A force of 50 N is applied at an angle of 30 degrees to the horizontal, and participants are discussing the tension in the string.

Discussion Character

  • Exploratory, Assumption checking, Problem interpretation

Approaches and Questions Raised

  • Participants are analyzing the components of the applied force and questioning the original poster's calculation of tension. There is a request for clarification regarding the diagram and the setup of the problem.

Discussion Status

Some participants have expressed disagreement with the original tension calculation and are prompting further analysis of the force components. The discussion is ongoing, with multiple interpretations being explored.

Contextual Notes

There is a mention of a diagram that is not visible to all participants, which may affect the understanding of the problem setup.

Homework Statement


A 10 kg block is at rest on a frictionless surface. The block is attached by a light inelastic string to a rigid wall. A force of 50 N is applied to the mass as shown in the diagram (attachment).

Homework Equations


The tension in the string is
a 148N
a 50N
c 43.3N
d 25N

The Attempt at a Solution


I think the tension on the string is 25N because sin30 is 0.5, and 0.5 x 50 = 25

I can't see the diagram yet. Perhaps you could describe the diagram.

That's incorrect. What are the horizontal and vertical components of that 50 N force?
 
There's a 10kg blck at rest on a frictionless surface. On the left of it is a string attached to it which is attached to the rigid wall as well. On the right a force of 50N is applied to it at 30 degrees to the horizontal.
