A boy of mass $40 kg$ is climbing a vertical pole at a constant speed. If the coefficient of friction between his palms and the pole is 0.8 and $g = 10 m / s^{2}$ , the horizontal force that he is applying on the pole is

Options:

Answer:

Solution:

Hints: Here $μ = 0.8$ Frictional force $= μ N_{1} = m g$ $N_{1} = \frac{m g}{μ} = \frac{400}{0.8} = 500 N$
