A body of mass $100\, g$ is sliding from an inclined plane of inclination $30^°$. What is the frictional force experienced if $\mu = 1.7$
A body of mass $100\, g$ is sliding from an inclined plane of inclination $30^°$. What is the frictional force experienced if $\mu = 1.7$
$1.7 \times \sqrt 2 \times \frac{1}{{\sqrt 3 }}N$
$1.7 \times \sqrt 3 \times \frac{1}{2}N$
$1.7 \times \sqrt 3 \,N$
$1.7 \times \sqrt 2 \times \frac{1}{3}N$
A body of mass $100\, g$ is sliding from an inclined plane of inclination $30^°$. What is the frictional force experienced if $\mu = 1.7$
${F_k} = {\mu _k}R = {\mu _k}mg\cos \theta $
${F_k} = 1.7 \times 0.1 \times 10 \times \cos 30^\circ $$ = 1.7 \times \frac{{\sqrt 3 }}{2} \times \frac{1}{2}\;N$
