## Homework Statement

Solve for the forces P and N acting on an object in equilibrium on an inclined plane.

Weight=10N, angle is 30 degrees

http://blob:https%3A//www.physicsforums.com/d431a152-5681-411b-ba57-809320539165

## Homework Equations

Trigonometry, i.e. sin, cos, tan rules. The 'Z' rule (amongst others) to determine angles.

## The Attempt at a Solution

I have attempted the problem (as done with similar problems, which were correct) however the answers seem to assume that the angle in solving P is 30.

I have used in the Parallel P=10tan60=17.32N. However the answer is given by 10tan30=5.77N. Is the answer wrong? Or have I made inaccurate assumptions?

In the perpendicular, N=10sin60=8.66N, however this is wrong also! The answer is given by 10/sin60

Thankyou for any help.
