1.	Consider an object of mass 2 kg resting on the floor. The coefficient of static friction between the object and the floor is mu_8= 0.8. What force must be applied on the object to move it?
Answer» Solution :SINCE the object is at REST, the gravitational force experienced by an object is balanced by normal force exerted by FLOOR. N = mg The maximum static frictional force `f_(s)^(max) = mu_sN = mu_s mg ` `f_(s)^(max) = 0.8 xx 2 xx 9.8 = 15.68 N` Therefore to move the object the external force should be greater than maximum static FRICTION. ` F_(ext) gt 15.68 N`
