Question

if angle of inclination of a wedge is 45 degree and a block of mass 2kg is kept on it stationary find the normal force​

Answer 1

Given,

m=2kg

θ=45

here; Normal force;N =mg cosθ

therefore, N= 2×10 cos45

since g =9.8 or 10 m/s²

and cos 45 = 1/√2

therefore N=20×1/√2

on rationalising it N=10√2 Newton

hope the answer will help you
