Homework Statement
A 2.00 kg block is held in equilibrium on an incline of angle = 75° by a horizontal force applied in the direction shown in Figure P4.50. If the coefficient of static friction between block and incline is µs = 0.300, determine the following.
(a) the minimum value of F
(b) the normal force exerted by the incline on the block

Homework Equations
F=ma
The Attempt at a Solution
For Y Component:
n-mgcos75=0
n=mgcos75
n=2.00*9.8cos75
n=5.07 N
It says this is wrong because of: Your answer differs from the correct answer by orders of magnitude.
For X
F-fs=0
F=usn=0
F=usn
F=0.300 x 5.07 N = 1.52 N
Does this look like I did it correctly?
