Question

the body of weight 20 n is on a horizontal surface minimum force applied to pull it when applied force an angle 60 with horizontal angle of friction 30

Answer 1

Tan 30°= coeff of friction

u=1/√3

Min force applied=limiting friction

F cos 60°=1/√3[weight - F sin 60°]

F/2+F/2=weight/√3

F=20/√3 N

Answer 2

Explanation:

this is the correct answer
