Question

Find the normal force exerted on a 2.3kg book resting on a surface inclined at 34∘ above the horizontal.

Answer 1

Can u draw it?

Answer 2

Anyway, u know the weight of ur book is=mg=2.3*9.8=?
Acting directly downward. Right?

Answer 3

Component of weight perpendicular to the plane=2.3*9.8*cos34=?

Answer 4

U know every action has an equal and oposit reaction.

Answer 5

So 2.3*9.8*cos34 is a force acting by book on the plane surface. And this is action

Answer 6

So reaction also will b =2.3*9.8*cos34N=. It will b a force on the book by surface. And this is called normal reaction. Right?

Answer 7

Response plz!!!!!!
