Answer:
In this case value of limiting friction force would be fr=µmgcos60 =0.7×mg×(0.866)= 0.606mg
But the Dowward force is mgsin30= 0.5mg
Here we can see that the downward force is less than tha maximum value of static friction. To make body balanced on incline the minimum friction required to be 0.5mg = 0.5×2×9.8= 9.8N
