Question

A block of mass m is placed on a wedge of mass N. Coefficient of friction between them is
u > col. The minimum acceleration of the wedge at which block appears stationary relative to
wedge is
N
AA
it's a physics question

Answer 1

Step-by-step explanation:

From FBD (shown in figure)

for max acceleration, macosθ=f+mgsinθ=μN+mgsinθ

or, macosθ=μ(mgcosθ+masinθ)+mgsinθ

or,a(cosθ−μsinθ)=g(μcosθ+sinθ)

∴a=

(cosθ−μsinθ)

g(μcosθ+sinθ)
