Question

Two bodies of masses 7 kg and 5 kg are connected by a light string passing over a

smooth pulley at the edge of the table as shown in the figure. The coefficient of

static friction between the surfaces (body and table) is 0.9. Will the mass kg

on the surface move? If not, What value of should be used so that mass 7 kg

begins to slide on the table?​

Explanation:

For equilibrium (f

s

)

max

=T..........(i)

From figure T=m

1

g..........(ii)

and N=(m

+m)g...........(iii)

Also (f

s

max

=μ

N...........(iv)

⇒μ
