Coefficient of friction between the block and the surface in each of the given figures being 0.4 , match Column - I and II . (Take g =10 m//s ^(2))

Coefficient of friction between the block and the surface in each of t

1.	Coefficient of friction between the block and the surface in each of the given figures being 0.4 , match Column - I and II . (Take g =10 m//s ^(2))
Answer» SOLUTION :Surface of LIQUID stays perpendicular the RESULTANT force . `tan theta = (ma)/(MG) = (a)/(g) , "" therefore theta = tan^(-1) ((a)/(g))`
