Question

A body of mass 5 kg is placed ob a rough horizontal surface if coefficient of friction is 1/√3 find what pulling force should act on a body at an angle 30to the horizontal so that the body just begins to move

Answer 1

Dear Student,

◆ Answer -

F = 25 N

◆ Explanation -

# Given -

m = 5 kg

θ = 30°

μ = 1/√3

# Solution -

Minimum pulling force so that body just begins to move is -

F = μ.m.g.cosθ

F = 1/√3 × 5 × 10 × √3/2

F = 5 × 10/2

F = 25 N

Therefore, body should be pulled with minimum force of 25 N.

Best luck dear...
