can anybody help me with this physics problem, im doin something wrong?

Question

A book with a mass of 2.0 kg is held in equilibrium on a board with a slope of 60.0 degrees by a horizontal force. What is the normal force exerted by the book?

Answer 1

for the information given one of the net forces is gravity and the other that balances it is friction on the board resulting is zero net force
also inertia an objects resistance to a change in its velocity.
the more mass the more inertia

Answer 2

that sucks. im so glad im done with physics.

my advice is to draw a picture, and use trig functions.
