A body of mass 100 g is sliding from an inclined plane of inclination

1.	A body of mass 100 g is sliding from an inclined plane of inclination 30^@. If mu= 1.7, then the frictional force experienced is
Answer» `(3.4)/(SQRT3) N` `1.47 N` `(sqrt3)/(3.4) N` `1.38 N` Solution :FRICTIONAL force `F = MU MG cos theta = 1.7 xx 0.1 xx 10 cos 30^@ = (1.7)/(2) xx SQRT(3)= 1.47 N`
